摘要
分析了大功率变频器常规的实现方法及存在的问题 ,进而提出用功率单元并联的功率合成技术 ,以增加变频器的功率 ,使变频器的容量不再受开关器件的容量限制 ,提高了可靠性和可实现性的方法 。
The usual implementing method and the existing problems about high power frequency converters are analyzed, and a power synthesis technology using parallel connecting power units is presented which enhances the power of frequency converter and exceeds in the limitation of switches' components capacitance and raises the reliability and actuality. The experimental results are given at the end of the paper.
