Abstract

The output voltage of boost DC/DC converting circuit will be increased when the duty ratio increased. Practically, when the duty ration increased to a threshold value, the output voltage will be decreased with the increasing of duty ratio. The boost DC/DC converting circuit was analyzed through state-space average method. Furthermore, it analyzed the main factors influencing boost DC/DC converting circuit voltage gain and put forward the effective working range of duty ratio of boost DC/DC converting circuit. Taking the boost circuit for example, the effective range of voltage gain of boost circuit was studied to set up the circuit for experiment. The experimental result verified the theoretical analysis result.
