| 摘 要： | 在分析正弦脉宽脉位调制(SPWPM)原理的基础上,详细介绍了通过TMS320F2812型DSP芯片来实现SPWPM控制波形的方法,芯片频率高达150 MHz,使得该方案与其他方案相比在高频链逆变电源中更具优势。1.2 kW/50 Hz输出、40 kHz开关频率的实验结果证实了该方法的可行性和有效性。

| Abstract: | On the basis of analyzing the principle of Sinusoid Pulse Width and Position Modulation(SPWPM),the method of producing SPWPM control waveform by using TMS320F2812 DSP is introduced.The method is superior to others when it was used in a high-frequency link inverter,because TMS320F2812 have a high frequency up to 150 MHz.The experi-ment of 1.2 kW/50 Hz output capability and 40 kHz switching frequency verify that the method is feasible and effectual. |
