| Abstract |
This paper presents a single ended push-pull (SEPP) high frequency inverter incorporating a reverse blocking active auxiliary quasi-resonant circuit using bipolar mode static induction transistors (BSITs) as active switches. This inverter can realize soft switching of the active switches over wider output power regulation range compared with the conventional SEPP inverter. It is performed by incorporating an auxiliary active switch to the conventional SEPP inverter to feed a required current for the soft switching operation of the main switches. The current fed to the main switches during their short switching period assists their soft switching operation over wide output power regulation range. The detailed evaluation of its operational principle and characteristics is carried out with the aid of computer aided simulation and the experimental result obtained by a bread board. |
