摘　　要：文中以大功率逆变电源为出发点,以组合式三相双降压半桥逆变电路为研究对象,提出了双极性三角波加中频正弦波的正弦脉宽调制控制技术,介绍了利用数字处理器TMS320LF2407实现SPWM的具体方法。试验结果证明,该方案实用可行,试验波形良好,谐波畸变THD<1%。In this paper, taking high power inverter as the starting point and three phase dual-Buck half bridge inverter circuits for study, the Sine Pulse Width Modulation（SPWM）technique which combines bipolar triangular wave and intermediate frequency sine wave is brought forward. The way to carry out the single pole double frequency SPWM is presented, which uses digital processors TMS320LF2407 of DSP. Finally, experimental result shows that the test wave is excellent and harmonic distortion THD 〈1%. So this way is applicable.
