| Abstract: | Focusing on the research of the novel ground power supply unit for airplanes,and majoring in the design of in-verter,this paper has studied a technique which is the combination of dual buck inverter circuit and bipolar Sine Pulse Width Modulation(SPWM).The merit of the dual buck inverter compared with the full-bridge inverter,and the dual buck inverter working pattern are described.Then the benefits of SPWM technique used in the high power inverter,compared with the hysteresis current control,are analyzed.At last,the simulation result and the empirical datum on an 115 V/400 Hz/10 kW inverter prototype proven this plan is feasibility for the high power inverter. |
