The output voltage of the topology is enhanced by increasing duty cycle. Recycling the energy of leakage inductances can help to reduce the voltage spikes on the power switches. For this reason, we can use a switch with low drain to source resistance. The output diode of this converter is turned off in zero current switching condition due to the leakage inductances. In this converter when the duty cycle and turn ratios are 0.57 and 1 respectively, the voltage gain is around 22. A comparison of the proposed converter with a conventional quadratic converter with similar characteristics was also performed. The results indicate that the proposed converter is more efficient than the traditional converter and can achieve ultra high voltage gain without working at extreme duty cycle.","PeriodicalId":213924,"journal":{"name":"2022 13th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125171613","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}

Beside, Common Mode Voltage (CMV) which leads to bearing currents (in motor drive applications) or leakage currents (in Photovoltaic applications) is another concern in the control of NPC inverters. To reduce the unequal voltage division between DC link capacitors in a Three Level NPC inverter, a new modulation scheme named Modified Virtual Space Vector Modulation (MVSVM) is proposed in this paper. In this modulation, virtual vectors are defined in way that both the objectives of DC voltage balancing as well as CMV reduction could be achieved. Unconditionally, this scheme can reduce the degree of inequality of the voltages across DC link capacitors with high accuracy for any modulation index and any load power factor. Moreover, common mode voltage is reduced to one sixth of DC link voltage. Simulation results using MATLAB software confirm the effectiveness of this modulation scheme.","PeriodicalId":213924,"journal":{"name":"2022 13th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116668567","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}

High voltage without more number of elements is achieved in the proposed converter. Moreover, the interlevead structure is used in this converter, causing low input current ripple. In addition, the voltage stress across power switches and diodes can be decreased, thanks to the passive clamp circuit. Meanwhile, due to the leakage inductance of BIT, not only turn-ON state for MOSFETS at zero current switching (ZCS) performace is provided but also ZCS turn-OFF state for all diodes is achieved.. Thus, reverse recovery problem of the power diodes is attenuated. Accroding to the above-mentioned advantages, the proposed converter is an interesting solution for high power applications. To verify the performance of the proposed converter PSIM simulation results of the proposed converter with 40-400V voltage conversion and 600W rated power are discussed in this paper.","PeriodicalId":213924,"journal":{"name":"2022 13th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126955283","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}

In this structure the PMs in the yoke and slot opening positions are shifted with respect to each other which provides lower reluctance path for armature flux. Moreover, the efficiency of this structure is improved compared to the conventional BFPM. The PMs are placed circumferentially in the stator and the stator modules are mechanically isolated from each other which increase the fault tolerance property of the structure during short-circuited phase operation. The design optimization process along with electromagnetic performance is assessed with finite element method (FEM) and the no/full-load characteristics are also provided.

The power switch turns on under zero-voltage-switching (ZVS) condition. Besides, the diodes currents are zero during their switching process (ZCS). These features significantly reduce switching losses and increase the converter’s efficiency. In addition, the voltage gain of this converter is high due to the presence of CL in its structure. The operating principles and steady-state operation are discussed in each time interval. In order to verify the theoretical discussion, computer simulation is performed in Cadence/OrCAD software.

Also, the critical characteristics of wireless power transfer are output power and efficiency. Therefore, the influence of coupling factor variation on different topologies at three coupling factors is scrutinized based on distinctive distances.

As some features, interleaving and cascading help the converters achieve high output voltage gain, low input current ripple, low-volume input inductor, and high reliability. Moreover, employing multi-winding coupled inductors improves output voltage gain, recycles the magnetic components stored energy, cancels circulating current, decreases switch voltage spikes, and reduces switch voltage stress.
