Designs and Applications of Modern AC PowerElectronics Circuits

Over the last decades, significant advances in powersemiconductor device technologies andlow-cost/high-speed control processors along withdemands of industries have reached beyond standardac/ac power converters with voltage-source invertersfed from diode rectifiers. Power electronicsconverters have been matured to stages towardimproving utility interface, compact physicalrealization, and increased high-power handlingcapability. This book addresses ac/ac powerconverters with specific superiorities: convertertype utility interface to obtain unity power factor,a matrix converter to realize compact size converter,and a current-fed converter with high-power handlingcapability. Based on the converter structures, thisbook provides new converter topologies and controlalgorithms to enhance their performance and providesolutions to conventional ones' drawbacks. Thedesigns and operational principles in this bookshould be useful to professionals in powerelectronics and motor drive fields, or anyone elsewho might be considering application of powerelectronics circuits to diverse application areas.
