2-25AMP,AC240V,PDA1系列PCB固態(tài)繼電器unionelecom,改變Ugs的大小，主電路的漏極電流Id也跟著改變。由于G、S間的輸入阻抗很大，故控制電流幾乎為0，所需驅(qū)動(dòng)功率很小。和GTR相比，其驅(qū)動(dòng)系統(tǒng)比較簡(jiǎn)單，工作頻率也比較高。此外，MOSFET還具有熱穩(wěn)定性好、工作區(qū)大等優(yōu)點(diǎn)。但是，功率場(chǎng)效應(yīng)晶體管在提高擊穿電壓和增大電流方面進(jìn)展較慢，故在變頻器中的應(yīng)用尚不能居主導(dǎo)地位。絕緣柵雙極晶體管（IGBT）IGBT是MOSFET和GTR相結(jié)合的產(chǎn)物，是柵極為絕緣柵結(jié)構(gòu)（MOS結(jié)構(gòu)）的晶體管，它的三個(gè)極分別是集電極C、發(fā)射極E和柵極G。工作特點(diǎn)是，控制部分與場(chǎng)效應(yīng)晶體管相同，控制信號(hào)為電壓信號(hào)Uge,輸入阻抗很高，柵極電流I≈0，故驅(qū)動(dòng)功率很小。而起主電路部分則與GTR相同。
