摘　　要：主电路的设计通常在设计的早期进行,一旦方案确定,不再轻易改变,因此设计时对各方面的问题应考虑周全,避免返工,造成时间和经费的浪费在主电路的设计中,通常需要综合考虑可靠性,成本,效率等多方面因素,甚至还有一些非技术性的因素,如结构设计等通过一个具体的电路。The design strategy of lugh-power resonant transition soft-switching techniques VVVF is described. A design ol mam-circent must be usually done in the forepart of designing, once a scheme is made certainly, it can't changed rashly. all aspects of the problems must he considered in order to keep from redoing and a waste of time and outlay Not only many factors such as reliability, cost, efficiency etc must be usually considered all-aroundly but indeed must some non - tech factors like designs for structure etc he thought of. The principles lor design of the main-circuit of high-power resonant transition soft-switching techniques VVVF are given by a idiographic circuit.
