What is IGBT?
•IGBT: I nsulated G ate B ipolar T ransistor (BJT + MOSFET)
Equivalent circuit symbol
IGBT
Low <12kHz Medium <40kHz High<150kHz
Difference IGBT vs. MOSFET:
•smaller chip size -> lower price
•softer switching, lower EMI
•temperature stable –
no significant loss increa
@ increasing Ta / Tj
流浪作业
•not suitable for ultra
