Short-circuit protection function test method 1 of IGBT drive circuit

Published:2011/4/8 1:29:00 Author:may | Keyword: Short-circuit protection, function test method, IGBT drive

The main problem IGBT solved is how to better protecting IGBT under the situation of over current, short circuit and over voltage. The error of over current generally need longer time to make the power supply to over heating, so the protection to it is mainly solve by main control board. In the diagram, C=10～470μF,Rlimit=10～100Ω,Creset =10nF.   (View)
