变频器电源主要用于交流电机的变频调速,其在电气传动系统中占据的地位日趋重要,已获得巨大的节能效果。变频器电源主电路均采用交流-直流-交流方案。工频电源通过整流器变成固定的直流电压,然后由大功率晶体管或IGBT组成的PWM高频变换器, 将直流电压逆变成电压、频率可变的交流输出,电源输出波形近似于正弦波,用于驱动交流异步电动机实现无级调速。
国际上400kVA以下的变频器电源系列产品已经问世。八十年代初期,日本东芝公司·先将交流变频调速技术应用于空调器中。至1997年,其占有率已达到日本家用空调的70%以上。变频空调具有舒适、节能等优点。国内于90年代初期开始研究变频空调,96年引进生产线生产变频空调器,逐渐形成变频空调开发生产热点。预计到2000年左右将形成高潮。变频空调除了变频电源外,还要求有适合于变频调速的压缩机电机。优化控制策略,精·功能组件,是空调变频电源研制的进一步发展方向。
