Stability And Performance Investigation Of DC to DC Resonant Converter - Softcover

Inhaltsangabe

DC-DC power conversion used in industry, medical, military and aerospace applications where the demand for compact power supplies grows significantly. Over the past several years, efficiency, voltage regulation and dynamic response have become the top concerns for power electronic converters. Efforts taken to increase the efficiency may lead to poor voltage regulation as well as dynamic response and also higher cost. DC-AC Resonant Inverters are finding their applications in high frequency AC distributed power systems.This thesis focuses on selecting a best converter topology by considering the performance parameters like efficiency and THD. The best suited inverter is selected and the same is analyzed for DC-DC resonant converter. The steady state stability of the DC-DC resonant converters is analyzed using state space technique. To improve the performance of DC-DC resonant converter closed loop control is implemented using PI and fuzzy controller, performance parameters like efficiency, settling time, rise time and steady state error are estimated by simulation software in MATLAB.The results are verified experimentally.
