Also the high side MOSFETs are P-channel for simplicity. Right high side MOSFET fully ON Forward. There are various H-Bridge designs and some use discrete components consisting of MOSFETs while other designs utilize a dedicated Integrated Chip IC H-bridge.
Learning H-Bridge motor works. An H bridge is an electrical circuit that changes the polarity of an applied voltage to a charge. Full h bridge circuits capable of a few amps can be purchased in convenient ic packages see pwm and h bridge.
10 illustrates the use of a motor power switch to turn off a generic h-bridge circuit. At the beginning turning a motor can seem like a simple job just connect the motor to the correct voltage rail and start spinning. The main function of this mosfet topology is to switch the load or the transformer primary in this diagram in a flip-flop manner.
Based on the above schematics simply switch motor voltage off change direction then motor voltage back on. A HIGH turns on Q7 driving its collector LOW and through CD4011b being used as an inverter produces a HIGH on the gate of Q5 turning the MOSFET on thus the motor will run. The complete circuit diagram for this H-Bridge using MOSFETs is given below.
