摘　　要：介绍一种前馈加双环控制技术的逆变器,它的双环控制包括一个电容电流内环控制和一个瞬时电压外环控制。通过分析该控制策略的工作原理,应用DSP TM320F2812对控制系统进行了设计。试验结果显示逆变器有很好的正弦波输出波形,快速的动态响应,优良的负载特性和高精度的输出电压。This paper presents a feed forward and double-loop control technology of inverter, its double-loop control including a capacitor current inner loop control and instantaneous voltage outer loop control. The principle of the control method is analyzed,and the realization of the control method based on DSP TM320F2812 is also given. The experiment resuits show that the inverter can achieve good sinusoidal output waveform, fast dynamic response, excellent load characteristic and high precision of output voltage,
