變頻器主電路一般是交流—直流—交流模式見(jiàn)圖3，外部輸入380V/50Hz的工頻電源經(jīng)三相橋路不可控整流成直流電壓信號(hào)，經(jīng)濾波電容濾波及大功率晶體管開(kāi)關(guān)元件逆變?yōu)轭l率可變的交流信號(hào)。在整流回路中，輸入電流的波形為不規(guī)則的矩形波，波形按傅立葉級(jí)數(shù)分解為基波和各次諧波，其中的高次諧波將干擾輸入供電系統(tǒng)。在逆變輸出回路中，輸出電流信號(hào)是受PWM載波信號(hào)調(diào)制的脈沖波形，對(duì)于GTR大功率逆變?cè)?，其PWM的載波頻率為2～3kHz，而IGBT大功率逆變?cè)腜WMzui高載頻可達(dá)15kHz。同樣，輸出回路電流信號(hào)也可分解為只含正弦波的基波和其他各次諧波，而高次諧波電流對(duì)負(fù)載直接干擾。另外高次諧波電流還通過(guò)電纜向空間輻射，干擾鄰近電氣設(shè)備。
