摘要
重点介绍了基于PIC单片机采用面积等效法产生SPWM控制波形的方法。通过具体试验,由SPWM来控制IGBT逆变系统的运行。最后给出了软硬件结合设计方法,结合试验结果波形进行谐波分析。此方法在UPS的设计中有较强的实用价值。
The method how to generate SPWM control waveforms with area equivalent principle based on PIC single chip computer is introduced. By the particular experimental system, the SPWM waveforms control the function of IGBT inverter. The method combining software with hardware is presented. The resultant waveforms and the harmonic of SPWM waveforms are analyzed. The analytic results show that the method has good practicality in UPS.
