DC motor control using 4-Quadrant chopper

Objective: SPEED CONROL OF A DC MOTOR USING H-BRIDGE H-Bridge is a circuit which enables the user to change the direction of rotation of the motor. The H-brdige is made up of four switches Q1,Q2,Q3,Q4 and four free-wheeling diodes D1,D2,D3,D4 The IGBT's act as electronic switches which can be either ON state or OFF state. When the…
