Abstract :
Thick-film hybrid technology is employed to fabricate a zero-current-switched, half-bridge, quasi-resonant converter for 300V dc off-line application. With a conversion frequency of 2MHz the converter delivers 80W at a power density of 21W/cu.in. This paper describes the theory of operation, detailed design rules and benefits of hybridization. Also described is a 2MHz hybridized gate drive.
