Abstract :
This paper presents the measured results of the output noise voltage and the spectrum of reflected conduction noise of a ZVS PWM series resonant power converter, and compares these noise characteristics with those of the conventional ZVS PWM forward power converter. As a consequence, it is clarified that the ZVS-PWM series resonant power converter achieves extremely low noise characteristics
