在展开路径上，两家龙头公司有所区别，但毕竟都将成为概括的产品处理计划供给商。英威腾将继续研发包括控制层和实行层在内的产品，并结束与变频器的联络，以保证原有出售路径在产品贮藏结束后，可以活络发起商场；汇川技术也面临着现有产品联络的疑问，一同在产能充分开释后，进行商场间横向拓展将成为其下一个主攻方向。
变频器的主电路大体上可分为两类:电压型是将电压源的直流改换为交流的变频器，直流回路的滤波是电容;电流型是将电流源的直流改换为交流的变频器，其直流回路滤波石电感。 
输入电压影响输出电压的几个政策方法。
1． 必定稳压系数。
A．必定稳压系数：标明负载不变时，稳压电源输出直流改动量△U0与输入电网改动量△Ui之比。既：K=△U0/△Ui。
