A power converter refers to an electrical circuit that converts electric energy from one form to another that is optimized for a particular load. Power electronic converters have been utilized in hybrid electric systems to achieve conversions from AC to DC, DC to AC, DC to DC, and AC to AC, which enable bidirectional power flow. They are primarily composed of solid-state switches including IGBT, power MOSFET, thyristors, power BJT, and lossless components such as capacitors and inductors. Precise timing control is needed for power electronic converters and systems. Power electronic systems are power systems that have an AC or DC source of electric power. This book unravels the recent studies on the control of power electronic converters and systems. It presents researches and studies performed by experts across the globe. The book will serve as a valuable source of reference for graduate and post graduate students.
