在展開路徑上，兩家龍頭公司有所區(qū)別，但畢竟都將成為概括的產(chǎn)品處理計(jì)劃供給商。英威騰將繼續(xù)研發(fā)包括控制層和實(shí)行層在內(nèi)的產(chǎn)品，并結(jié)束與變頻器的聯(lián)絡(luò)，以保證原有出售路徑在產(chǎn)品貯藏結(jié)束后，可以活絡(luò)發(fā)起商場；匯川技術(shù)也面臨著現(xiàn)有產(chǎn)品聯(lián)絡(luò)的疑問，一同在產(chǎn)能充分開釋后，進(jìn)行商場間橫向拓展將成為其下一個主攻方向。
變頻器的主電路大體上可分為兩類:電壓型是將電壓源的直流改換為交流的變頻器，直流回路的濾波是電容;電流型是將電流源的直流改換為交流的變頻器，其直流回路濾波石電感。 
輸入電壓影響輸出電壓的幾個政策方法。
1． 必定穩(wěn)壓系數(shù)。
A．必定穩(wěn)壓系數(shù)：標(biāo)明負(fù)載不變時，穩(wěn)壓電源輸出直流改動量△U0與輸入電網(wǎng)改動量△Ui之比。既：K=△U0/△Ui。
