| Abstract: | It introduces a kind of IGBT drive circuit---SKHI21, which can measure the under
- voltage of the drive power. Primary and secondary is isolated by the pulse transformer, which can drive two IGBTs in the upper and the down tubes of the drive half- bridge and can run with only one DC power source. Besides, it is able to protect against the output short circuit and protect efficiently IGBT by soft switching off. The article analysises its inner scheme and its operation. Experiments show that the said crive circuit is easy to use, reliable with excellent drive and protection performance. |
