摘  要:本文简述了单相逆变电路的工作原理,分析其驱动信号生成的两种分立元件控制电路;提出利用数字信号处理器实现正弦脉宽调制,并结合德州仪器公司的TMS320LF2407介绍几种方案的具体实现方法。通过实验验证,逆变电源频率稳定度,谐波失真度,已在车载发电系统中得到应用。The principle of single-phase inverter is briefly introduced in this paper. Then two kinds of circuits with discrete components which generate the driving signal of the inverter are analyzed. Sine Pulse Width Modulation (SPWM) based on Digital Signal Process (DSP) is proposed. And several methods are presented on the platform of TMS320LF2407 manufactured by Texas Instrument. The experimental results show that the output frequency stability coefficient is less than 0.02% and total harmonic distortion is less than 3%. This solution has been applied to the vehicle mounted power system.
