The frequency fr of resonant converter is fixed, it needs to change the switching frequency fs when the voltage regulates.As to practical current resonant converter,the conduction time of switch is constant, so fs must be reduced when the output voltage increases and the load is light.The sizes of transformers,reactors and other magnetic components are inverse proportional to the switching frequency, so we do not expect it to reduce. 　　Now there is a part resonant converter,this converter solves the problem of high voltage of switching components in the voltage resonant converter.
