NOTE：Only the graphical symbol for N-channel IGBT is used in this standard. It equally applies for the measurement of P-channel devices. In the case of P-channel devices polarity must be adapted.文章来源：http://www.igbt8.com/jc/147.html
3.2.1 绝缘栅双极晶体管 IGBT
Transistor has a conduction channel and a PN junction. The current flowing through the channel and the junction is controlled by an electric field resulting from a voltage applied between the gate and emitter terminals.
NOTE：With collector-emitter voltage applied, the PN junction is forward biased.
