The feed-forward control scheme based on SPWM matrix converter is proposed. As a device without DC line, the AC line side abnormal inputs can deteriorate its output characteristics. Tri-carrier is prior modulated by measured envelop of line voltages, to let the pulse width of SPWM get different compensation in each pulse. This paper analyzes compensation(More)
In terms of the conventional inverter doesn't match all unbalanced loads, a topology and strategy of nature- decoupling in circuit and magnetic circuit is proposed for aeronautic and military equipment field. Each phase voltage is controlled independently by PI controller and double-loop controller with voltage and current instantaneous feedback, and phase(More)
