#157326 - Drive IGBT using AT89C51 |
I am trying to build three phase inverter ciruit to drive three phase induction motor upto 1hp with rated current not more than 5A.
I will convert single phase 230V 50hz to dc using bridge rectifier.I am not sure about the filter ciruit.This DC voltage is fed to inverter. The IGBT are to be fired using 180 degree conduction mode with three IGBT on at any given time. The IGBT module is 6MBI4500-120 with 15A and 600V. The Vge voltage is 15V. The IGBT driver circuit is HPCL316J. Can I generate the 15V from the same supply. 8051---->IGBT driver---->IGBT module Can I use descrete IGBT as the voltage and current requirement is not too high.But the problem with descrete module is its protection ciruit and heat sink. What can be the PCB design consideration for High voltage circuits. |
