| Abstract: | 400 Hz inverter is the special powers supply used in the aeronautical system. This paper designs a threephase SPWM inverter supply based on TMS320F2812. And the double closed-loop of voltage and current control structure is used to reach the control goal. Then the accurateness and feasibility of the control tactics are analyzed deeply. Some crucial parameters in the circuit and simulation results are provided for certification. Also hardware circuit is designed preliminarily. The experiment result proves that the inverter supply design has an engineering practicability. |
