H Bridge Transistor Circuit. Working of this circuit is very easy to understand. This configuration of transistor has been used in h bridge to drive a motor in both clockwise and anticlockwise direction.
So motor will rotate in one direction. But unable to control direction of the motor. So we need a h bridge of transistors in order to control speed as well as direction of the motor efficiently.
The description of the circuit based project can be divided into two parts.
This circuit derives its name from the english alphabet h which closely resembles the circuit pictorially. Because the single transistor motor driver was able to control the speed of motor. Here s the concept of the h bridge. The diodes d1 to d4 provide a safer path for the back emf from the motor to dissipate and thus it protects the corresponding bipolar transistors from damage.
