Using IRFP250 power tube H-bridge motor drive circuit

Published:2011/7/8 2:42:00 Author:Fiona | Keyword: power tube, H-bridge motor drive | From:SeekIC

The drive circuit of electromotor includes a FET bridge circuit, FET base drive circuit,current sensor of motor drive circuit and the relay. FET bridge circuit mainly consists of four high-power MOSFET power tubes,it requires that the power tubes have good switching characteristics,can withstand higher drive current and have a long life.According to motor power parameters and power tube limit parameters and the electrical characteristics,we use four the same N-channel IRFP250power tubes to form the H-bridge circuit.
