The goal of this work is to control the speed of the PMDC motor. Also the motor can be control in both the directions i.e. forward as well as reverse direction along with regenerative braking .The specialty is that the power circuit is made up of international rectifier IGBT IRG4BC20S which have low operating frequency upto 1 KHz. It consists of completely innovative logic circuitry which uses Pulse Width Modulation, for producing control pulses of variable width, and a Direction Changing Logic technique for rotating of motor in both directions also it doesn’t involve any triggering circuit. The class E chopper circuit is used for four quadrant bi directional operation.

Keywords: PMDC motor, Speed control, PWM (SG3524 ) as controller, 4Q class E chopper
