H Bridge Circuit Diagram. The h bridge configuration is a common way to change the direction of the power supply. Operating supply voltage up to 46 v.
Figure 1 shows the schematic diagram of the h bridge dc motor driver. 26 the right mosfets q2 and q4 in the simplified diagram above select the motor rotation direction. A dc motor is connected between the two commons.
