| Abstract: | The operational principle and control strategy of a SPWM high frequency aviation inverter are introduced in the paper. A novel voltageshiftingcomparison method is first proposed and studied. Two of UC3879 chips are used to control the aviation inverter, the control system becomes simple and high stable. Experimental results show that the design is effective and feasible. |
