The proposed technique offers advantages including very simple power circuits, simple control and protection, and very-high-quality input currents. The power factor correction method is described, and the analysis, design, and performance obtained from a buck-type single-ended resonant converter with three-phase supply based on this principle are outlined. Results for a 2.5 kW/40 kHz prototype converter, utilizing a single high-speed GTO as the active switching device and operating directly offline from a 415 V three-phase mains supply, are presented to verify theoretical predictions. The measured input current waveforms drawn from the three-phase supply are sinusoidal with approximately unity power factor.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120936938","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}

This new configuration extends the standard layout of conventional PWM voltage source inverters by adding a fourth branch devoted to controlling the machine neutral voltage. Computer simulations are used to show the inverter modes of operation.

A MOSFET-based power conditioning unit (PCU) of 1 kW capacity is discussed in detail along with a control algorithm to track the maximum power point. Maximum power from each PV array is extracted in spite of any mismatch in the array characteristics. One system controller is capable of handling several PCUs, simplifying the design and resulting in a lower cost of the system. It was observed that the maximum power point tracking (MPPT) increases the power output by abut 10% over a day as compared to the direct connection.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127484267","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 scheme for combining the deadbeat control with a current source compensator is proposed, and the control mechanism is analyzed. A current source compensator is used to compensate the voltage drop at the firing instant of a triac-controlled resistive load. The PWM is determined at every sampling instant by the proposed algorithm. Simulation results show that the scheme can produce nearly sinusoidal waveforms for nonlinear loads.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"321 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123686069","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 results of the analysis are used to define design guidelines that minimize the circulating energy in the converters and maximize their efficiencies and power densities. The analyzed converter topologies include the half-bridge zero current switching quasi-resonant converter (HB ZCS-QRC), the half-bridge zero-voltage-switched multiresonant converter (HB ZVS-MRC), the constant-frequency half-bridge zero-voltage-switched multiresonant converter (CF HB ZVS-MRC), the HB ZVS that uses the magnetizing inductance as a resonant element (HB ZVS-MRC (L/sub M/)), and the full-bridge series-parallel-resonant converter (FB SPRC). The results of the analysis show that the HB ZCS-QRC and the soft-switched HB ZVS-MRC (L/sub M/) circulate relatively small amounts of power. However, the circulating power in the HB ZVS-MRC, CF HB ZVS-MRC, and SPRC is found to be considerably larger. The analysis is used to generate sets of characteristics for each converter that can be used in their design optimization based on the minimization of the circulating power.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125530231","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}
