ABSTRACT:
A parallel resonant circuit for use in a series resonant converter. The parallel resonant circuit is located between the clamp diodes and the dominant series resonant capacitors of the converter. The parallel resonant circuit has a predetermined resonant frequency which is set to be above the telephone voice band. The circuit limits the operating frequency of the converter for light loads to be no lower than the parallel resonant frequency.
