Abstract

This paper presents a high-efficiency class DE tuned power oscillator, along with the analysis, design procedure, and experimental results. It consists of a class DE inverter and a feedback-loop for phase matching and is especially applicable for high frequency performance because it minimizes the power dissipated when turning ON each MOSFET. In contrast to conventional inverters, the proposed oscillator needs an additional complicated circuit including a driver circuit to start the oscillation. The measured efficiency was over 90% at the operating frequency of 1.0 MHz and output of 2.3 W
