SPEED CONTROL USING H-BRIDGE AND DC-7 BLOCK

Objective: 1) SPEED CONTROL OF DC MOTOR USING H-Bridge. The H-bridge consists of four IGBT/Diode pairs. Two transistors are switched simultaneously: Q1 and Q4 or Q2 and Q3. When Q1 and Q4 are fired, a positive voltage is applied to the motor and diodes D2-D3 operate as free-wheeling diodes when Q1 and Q4 are…
