Hybridized off-line 2-MHz zero-current-switched quasi-resonant converter
IEEE transactions on power electronics, 1989•ieeexplore.ieee.org
Thick-film hybrid technology is used to develop a half-bridge, half-wave, zero-current-
switched quasi-resonant converter for 300 V DC offline application. With a conversion
frequency of 2 MHz the converter delivers 80 W at 78% efficiency with a power density,
excluding heat sink, of 21 W/in/sup 3/. The operation and detailed electrical and hybrid
design of the circuit are described. Also described is a 2 MHz hybridized gate drive.<>
