摘要： An asymmetrical pulse width modulated resonant DC--DC converter exhibiting improved zero voltage switching characteristics is disclosed. The converter includes a chopper circuit to convert the DC input voltage to a high frequency AC voltage which, in turn, is fed to a high frequency transformer whose secondary AC is rectified and filtered to produce a stable DC output. A compensation network is placed between the input and the chopper circuit which provides zero voltage switching of the converter over a wide input voltage range.
