A typical microinverter consists of a DC/DC conversion stage, followed by an inverter stage. Dual active bridge (DAB) converter appears to be a promising candidate for use in the DC/DC converter stage in a microinverter since it offers several features like high voltage gain, galvanic isolation, zero voltage switching, etc., which are highly desirable for microinverters applications. A micro-inverter topology is presented in this paper which is based on the dual active bridge converter. The proposed topology also incorporates active power decoupling (APD) by supplying the low frequency component of single phase AC power drawn by the load without using any extra switch. APD allows reduction in the required value of DC link capacitance without having a large voltage ripple. This obviates the use of electrolytic capacitors, which generally have a short operating life and are considered a weak link in power electronic systems. The paper describes the modelling of DAB for closed loop control, and the control system for 100 Hz power decoupling. The proposed microinverter topology has been simulated in PLECS, and the simulation results are presented here.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116927757","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 partial feedback linearizing scheme is applied for simplifying and linearizing this detailed dynamical model of synchronous generators in an SMIB system using nonlinear coordinate transformations that cancel nonlinearities within the system. A linear state feedback controller is then used to design for the partial feedback linearized synchronous generators. The final excitation control law include nonlinear terms and the linear state feedback control law where these nonlinear terms appear from nonlinear coordinate transformations that cancel nonlinearities for making the partial feedback linearized SMIB system independent of operating conditions. The stability of dynamics that do not transform during the feedback linearization process is also analyzed in this paper. Finally, simulation studies are carried out to evaluate the performance of the controller by applying the most severe three-phase short-circuit fault at the terminal of the synchronous generator as well as at the middle of a transmission line and results are compared with a traditional power system stabilizer (PSS).","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125874660","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}

Here a lithium-ion (Li-ion) battery, having the benefits of fast charging, higher depth of discharge (DOD), and significantly lower maintenance cost, is preferred over the traditional lead-acid battery. However, it increases the vehicle's initial value, but it becomes cost-effective and economical in the long run. The improved driving range of the vehicle allows the owner to earn more by increasing the daily number of shifts. The regenerative braking strategy is also implemented that reduces carbon emission and a step towards green mobility. The energy regeneration technology significantly improves the driving range of the vehicle. The maximum power extraction of the solar PV panel is achieved by the Cuk converter, ensuring continuous input and output current. Thus, the life span of the battery is largely improved. To make the system robust and cost effective, a novel position sensorless control is also implemented. This system is easy to control and can be implemented in the field.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125901120","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 conventional 12-pulse rectifier does not meet the IEEE-519 standard and hence the active power factor correction technique is employed to mitigate the harmonics. The proposed system employs two diode bridge rectifiers, each followed by a SEPIC converter, by controlling the SEPIC converter inductor current, the input line current of the rectifier can be approximated to a sinusoidal waveform. A zigzag connected autotransformer is used as a phase-shift transformer in order to provide a phase shift and inherently blocks the zero sequence components. This method reduces the total harmonic distortion and also decreases the size of the system. The proposed configuration is analyzed and simulated in the MATLAB Simulink and also implemented in laboratory. The results show that the proposed method improves the power quality by reducing the total harmonic distortion (THD) in the input line current.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124876991","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 converter provides successful buck-boost conversion with low source current ripple which results in reduced source side filtering requirements. The key feature of this converter is the extended bucking duty-ratio range. State-space and steady-state analysis is presented to identify the performance features of the proposed converter. For arriving at the voltage gain transformation ratio, continuous inductor current mode of operation is considered. L, C component equations are derived thereafter. Small-signal transfer function derived after state-space analysis is then obtained and controller designing is performed. A 24 to 42 Watt, 50 kHz prototype of the proposed converter is also built for experimentation. Load voltage adopted is either 15 or 42 V. For powering the converter prototype, a dc source supplying 24 V is used for both simulation and experimentation.
