Abstract :
This paper clarifies the principle of the surge voltage in the diode rectifier that is connected to the transformer in the isolated DC-DC converter. In addition, the design method of the RC snubber circuit is discussed by using the equivalent circuit that is consisting of the transformer, the snubber circuit and the diode. Finally, the experimental results are provided to validate the design method.
