摘　　要：文中介绍了应用高性能数字信号处理器(DSP)TMS320F28335输出正弦波的原理和方法,其中详细介绍了借助28335内部的正弦脉宽调制(EPWM)模块输出单臂/双臂斩波、带/不带同臂互补的四种驱动信号的方法,最后搭建实验平台对理论分析和仿真结果进行验证,实验结果表明利用该控制器的逆变系统可以输出满足工程需要的50 Hz正弦波。This article describes the principles and methods of the output sine wave based on high-performance digital signal processor （DSP） TMS320F28335, which is introduced in detail how to take advantage of TMS320F28335 chip peripheral sinusoidal pulse width modulation（EPWM） modul to generate single/double-armed chopped and with/without com- plementary same-arm drive signals. Finally, the experimental platform is set up and the theoretical analysis and simulation results are verified, the experimental results are presented to demonstrate that using the controller output inverter system can meet the engineering need of 50 Hz sine wave.
