With the development of the pulse power. Numerous questions had emerged example,some processing engine bed ’s electricity need to adjust quickly; also, some electroplate need other properties and so emerge of these questions had promoted the development of the high-frequency pulse only high-frequency pulse power had plished these questions perfectly,but also rise the average power of the pulse power and decrease the volume of the power as well as lower the price of ,the high-frequency pulse power would play an important part in our society before text mainly use the ---------------------------------
