Abstract

A new control method of resonant DC/DC converter with Class DE inverter and Class E rectifier is proposed, which can easily regulate the output voltage for both wide load and line variations while the operating frequency is fixed. It is a pulse-width modulation (PWM) control, i.e., varying the dead time duty ratio of Class DE inverter at a fixed operating frequency. The measured efficiency was over 80% with 2.26 W output power at an operating frequency of 1.00 MHz
