Abstract

This paper presents a minute analysis and experimental results of phase-controlled resonant DC-AC inverters with class E amplifiers and frequency multipliers. The circuit is composed of two identical class E amplifiers or frequency multipliers, which are used as DC-AC inverters and connected in parallel. The two inverters are driven at the same switching frequency, and the overall output power of the circuit can be controlled by varying the phase shift between the drive voltages of the two inverters. The circuit can regulate the output voltage at a constant switching frequency. The measured efficiency was over 93% at an output power of 0.98 W and a switching frequency of 0.5 MHz for both of the inverters with amplifier and frequency doubler
