Abstract

In this paper, novel zero-voltage-transition(ZVT) synchronous buck converter of pulse-width-modulation(PWM) method is proposed to utilize auxiliary circuit. In this proposed scheme, designed to operate low output voltage for portable system and applied synchronous scheme to improve efficiency. Also proposed circuit is designed to do soft-switching operation in every switch. In this paper, the circuit operation is explained and analysed, and design guidelines are presented. To verify the availability of the proposed circuit, experiment and simulation is carried out.
