摘　　要：由于SVPWM技术具有直流电利用率高、场效应管损耗小且易于数字控制等优点,将其引入到由DSC控制的单相逆变系统中,可以实现高速动、静态响应特性的AC输出.DSC运用ePWM模块产生带死区控制的SVPWM信号,通过高压驱动芯片IR2110调制单相H型逆变桥的输出交流电,控制器通过高速PID进行反馈调节,利用eCAP进行相位跟踪调控,使系统达到具有自适应能力的瞬时稳态调节效果.Because of having the virtues of higher utilization rate of DC voltage,small loss of FET,and easy-to-realize through digital control,space-vector PWM technique is applied to the single-phase inverter system controlled by DSC to output AC with high speed and static response character.With the utilization of ePWM module,the DSC generates SVPWM signals with dead-time control,which modulates AC output from the single-phase H-bridge inverter with the high-voltage driver chip IR2110.By carrying out high-speed PID feedback regulation,tracking and regulating the AC＇s phase with the eCAP,DSC makes the system basically achieve the purpose of the instantaneous steady-state regulation with the ability of self-adapting.
