Abstract :
Modeling for the series resonant power converter (SRC) pulsewidth-modulated or current-controlled for low switching loss is developed in the discrete time domain. An optimal trajectory control which can provide the fastest response for the converter is proposed and modeled in combination with the converter. Based on the developed modeling, the root locus technique is employed to analyze the stability and dynamic characteristics of the controlled converter
