WOONYOUNG云永WYES云永功率控制器：,,即Ics≈Uc/Rc時，GTR便處于深度飽和狀態(tài)（Ics為飽和電流）。這時，GTR的飽和壓降Uces約為1-5V。GTR處于飽和狀態(tài)時的功耗是很小的。上例中，設Uces=2V，則Ics=Uc/Rc=200/10A=20APc=UcesIcs=2*20W=40W可見，與放大狀態(tài)相比，相差甚遠。⑶截止狀態(tài)即關斷狀態(tài)。這是基極電流Ib≤0的結果。在截止狀態(tài)，GTR只有很微弱的漏電流流過，因此，其功耗是微不足道的。GTR在逆變電路中是用來作為開關器件的，工作過程中，總是在飽和狀態(tài)間進行交替。所以，逆變用的GTR的額定功耗通常是很小的。而如上述，如果GTR處于放大狀態(tài)，其功耗將增大達百倍以上。所以，逆變電路中的GTR是不允許在放大狀態(tài)下小作停留的。
