A three-phase intermediate frequency aviation inverter power with single chip microcomputer and SA8282 as its main controller is designed in this paper. The overall structure of the proposed system is given. The working principle and design method of the main circuit are presented in detail. Among the control circuit design process, the generation of SPWM waveforms, the main parameters design of SA8282, the digital PI regulation and the software design process are analyzed. The proposed control strategy has been implemented on a 9KVA, 400Hz three-phase power supply. Experimental results show that the three-phase output voltage waveforms are quite good, the performance of the supply meets the demand.
