Abstract

A novel dual Boost/dual Buck AC-AC converter which is very suitable for the variable-frequency power system of airplane (360 Hz-800 Hz) is proposed in this paper. It is constructed by directly connection of a dual Boost rectifier and a dual Buck inverter which inherit the merits of high reliability and efficiency of them for no hidden danger of shoot-through and no freewheeling current flows through the body diodes of power switches. The operational principle and control method are briefly talked about first; then the method of designing inductors is deduced, also the principle of choosing DC bus voltage and capacitors are proposed. At last, a 1 KW laboratory prototype is designed. Both experimental and simulation results verified the validity of the presented circuit.
