A modified synchronous reference frame (SRF) based controller for the series active filter allows injection of a controlled percentage of the higher harmonic load currents into the supply, in compliance with the IEEE 519 harmonic current standards, thereby reducing the passive filter terminal voltage THD. This implementation retains all the desirable features of the original SRF controlled hybrid series active filter system. It reduces the rating and size of the passive filter system and allows the use of simpler passive filter system structures such as only a simple high pass passive filter or a simple power factor correction capacitor as the passive filter system. Simulation and experimental results are used to establish the functionality and performance of the SRF controller and the modified SRF controller for the hybrid series active filter system.<<ETX>>","PeriodicalId":358822,"journal":{"name":"Proceedings of IEEE Power Electronics Specialist Conference - PESC '93","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116763803","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 operation allows zero current switching (ZCS), which is convenient for bipolar devices. The capacitive output filtering reduces the recovery effect of the rectifier diodes and is suitable for high output voltage applications. A closed form solution is found for this converter, based on state space analysis using energy concepts. This approach simplifies the mathematical operations, and gives better physical insight into the system variables. Based on the model, the steady-state characteristics of this converter are derived by a simulation program. They are discussed and compared with those of the series resonant half-bridge power converter (SRHC). The optimum converter parameters are found for given design requirements using computerized optimization routines. Several design examples are presented and compared with SRHC. The validity of the model is verified by SPICE simulations.<<ETX>>","PeriodicalId":358822,"journal":{"name":"Proceedings of IEEE Power Electronics Specialist Conference - PESC '93","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125342591","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}

Several bridge-type converters which achieve soft-switching of IGBTs with the help of the fast-switching MOSFETs are proposed.

The steady state as well as the dynamic performance of the RSM are investigated. Two control strategies are dealt with. These are the constant current phasor angle control method and the constant-current-in-d-axis (field axis) control method. Regarding the former it is found that for both maximum torque and power factor control, constant current phasor angles can be used. These angles however are found to be much larger than was theoretical derived. A new control method is investigated whereby the apparent flowing towards the machine is minimized. Constant-current-in-d-axis control also proved to be an effective control method.<<ETX>>","PeriodicalId":358822,"journal":{"name":"Proceedings of IEEE Power Electronics Specialist Conference - PESC '93","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117041563","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}
