In this paper, a flyback based resonant converter is proposed in order to obtain a variable pulsed output voltage ($mathbf{2}.mathbf{5} mathbf{kV}-mathbf{10} mathbf{kV}$) fed from an input voltage of 230 V, 50 Hz AC supply. Ozone generators are low power applications with the pulse repetitive rate limited to 1 kHz to 5 kHz and the pulse width limited to $mathbf{10} mumathbf{s}$ to $mathbf{30} mumathbf{s}$. For ozone generation, the oxygen is passed through a dielectric barrier discharge chamber, which is subjected to a high voltage across its electrodes which supply the energy for the micro discharges to take place. In this paper, the high voltage pulses are obtained through a resonant circuit topology with a transformer in the output stage to boost the output voltage and give isolation. The resonant capacitor is charged through a flyback circuit after every switching instant of the resonant circuit to the desired voltage magnitude, ensuring charging time constraint. In the proposed work, the high voltage pulses of desired voltage magnitude with pulse repetitive rate and pulse width are designed and validated through simulation results.","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115278112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed inverter can limit the charging current of switched-capacitor units. Voltage balancing of each capacitor is not required for the inverter. The capacitor voltages are automatically adjusted to the desired levels in each cycle of the ac voltage output. A step-change in the voltage is generated by switching the capacitors in series one after another. Usually, SCMLIs have a front-end switched capacitor configuration and a back-end full bridge inverter. The converter in the front-end steps up the dc voltage, and the back-end inverter generates ac output voltage. The elevated voltage from the front-end converter increases the voltage stress in the back-end H-bridge configuration. The proposed inverter doesn't need a back-end H-bridge inverter to generate ac output. A small inductance is introduced in series to the source to minimize the initial charging current in the multiple switched capacitor configurations. A lower dc capacitor charging current increases the overall efficiency and decreases the switching loss in the inverter. Circuit configuration, pulse width modulation (PWM) method, and operation principle are explained in detail. Finally, a simulation of the nine-level inverter is done in MATLAB, and simulation results validate the expected performance.","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124699420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the integration of MMGs serve uninterruptable power supply to the customers increasing system reliability. The deeper infiltration of the MMGs changes the fault current characteristics when integrated in the smart distribution system network. The operation of MMGs also impact the direction and level of fault currents. The increase in the fault current contribution level may lead to false conventional relay tripping. Thus, the conventional differential overcurrent based protection methods fail to operate for the smart distribution system consisting MMGs, as these methods were usually suggested for radial networks. Moreover, the detection of low impedance as well as high impedance faults is very important in the area of differential protection in smart distribution network consisting MMGs. Thus, a novel fault detection index utilizing positive sequence angle ratio of pre fault and post fault currents, is proposed in this paper. The novel fault detection index helps in detecting and classifying the low and high impedance faults accurately ensuring better reliability. The method proposed in the paper is validated on the modified IEEE-13 bus system using Real Time Digital Simulator (RTDS).","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114067774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the traditional methods for assessing the effects of ageing, such as the degree of polarisation measurement of kraft paper, are destructive. Transformers' ageing characteristics can be extracted from dielectric response analysis using frequency domain spectroscopy's low-frequency band. However, measuring frequency domain spectroscopy (FDS) in low-frequency regions is time-consuming. This research developed a unique deep convolutional neural network (DCNN) based ageing state identification approach by converting FDS into a visual domain using Markov Transition Field (MTF) to ascertain the hidden ageing attributes. Thus enhancing the ageing features and automatic feature extraction is utilised for ageing state diagnosis. The proposed MTF-DCNN method has a 96.60% diagnosis accuracy across five ageing categories. It also provides an automatic feature extraction-based network for a detailed evaluation of the transformer's insulation health.","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"708 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123838830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dual Active Bridge (DAB) with medium frequency transformer is used to reduce the size of the interface between the permanent magnet synchronous generator (PMSG) and the high voltage DC (HVDC) line. The series connection of the DAB output capacitors helps in achieving the platform-less operation by eliminating the need for a low frequency step-up transformer, but leads to a severe mismatch of the DAB output voltages due to the unequal wind power inputs at the wind turbines (WTs). Overvoltage at DAB output can be avoided by curtailment, i.e. operating the turbine away from the maximum power point tracking (MPPT) using WT inertia, which leads to loss of available energy. The possible use of ultra-capacitors (UC) to reduce the loss in energy is demonstrated in this work.","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"414 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123910166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A control methodology for the snubber is proposed that reduces the snubber switching frequency and makes the clamping voltage a function of input voltage that helps in reducing voltage stress, voltage ringing magnitude on the secondary diodes, and hence the EMI.

The primary function of an avionics grade power supply is to provide the desired regulated output voltages and comply with the various power quality and switching bus transients (also called holdup time) [1]–[3]. These switching bus transients call for energy storage components like capacitor banks, which can store energy during nominal operation and deliver the energy back during these power interruptions. The conventional way to achieve the holdup time is by having the holdup circuitry on the primary side. There have been multiple primary side holdup methodologies for extending the holdup time, like boosting the holdup voltage circuitry. [4]–[11]. There are many drawbacks and limitations associated with conventional design for holdup solutions where the holdup circuit is based on the primary side of the power supply. The holdup capacitors need to be designed to take care of the efficiency of both the step-down buck converter and the DC-DC converter, which are used to regulate the output from the input bus. In the case of a dual input bus system, the galvanic isolation between the two input buses dictates the use of two separate holdup circuitries for the two input buses. Another major drawback with primary side holdup circuitry is that the higher boosted voltage will result in the implementation of safety requirements which will call for a bleeder circuit to dissipate the holdup capacitor energy to reduce the boost voltage to a safe limit. The design solution explained in this paper overcomes the limitations and drawbacks of conventional holdup design solutions with less form fit, lower cost, and higher reliability. The solution is implemented and tested in a dual input bus airworthy system where electrical isolation is needed between the input power buses and the input power bus to output. The holdup circuit architecture discussed in the paper is based on the secondary side and is referenced to the secondary return (chassis). This unique architectural change ensures that only one set of holdup circuitry is sufficient to meet the redundant bus power interrupt requirements without compromising the isolation requirements and higher efficiency.","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129446635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
