摘要
研究了一种数字控制逆变器,采用智能功率模块PS21865,减少了系统的复杂性,提高系统的可靠性。分析了单极性SPWM控制策略的优点和应用场合,给出了基于转速/电流双闭环控制的SPWM调制策略,完成了对直流变频空调压缩机的控制,并给出实验波形。
A SPWM inverter based on numeric control was researched. As the application of intelligence power module, the system was simple in design and reliable in performance. The advantage and purpose of the unipolarity SPWM control strategy were analyzed, and the strategy based on double - loop control was shown. The waveform got from the experiment on an air - condition compressor was given.
