Abstract

A voltage converter transmits energy in multiple stages using a charge pump so as to decrease the voltage rating of the secondary side of the transformer and reduce the size of the transformer. Meanwhile, the voltage converter stores and recycles the leakage inductance energy by using a snubber circuit so as to increase the efficiency.
