【 摘 要 】

This paper aims to improve the efficiency of a dc-dc buck converter. It enables a synchronous rectifier buck converter to realize zero voltage switching in light load condition. The replacement of output rectifier diode by MOSFET can minimize conduction losses and increase the efficiency of the circuit. The control technique introduced in this paper enables a SR buck converter to carry out ZVS in light load condition to increase efficiency. No extra auxiliary switches or RLC passive components are required.
