These are darlington transistors that can deal with high power outputs. The 2 types of transistors we will use are the TIP107 PNP transistors and the TIP102 NPN transistors. In total, we use 4 different transistors, 2 PNP transistors and 2 NPN transistors. These are transistors provide very good current gain and transistors Since motors run off a good amount of current, we will use high-current gain and high-power transistors. So in this circuit, we will build an H-bridge simply with bipolar junction transistors. You may also just be interested in knowning how an h bridge works. You can also build it with discrete and simple components such as with transistors andĮven though it's almost invariably simpler to use an IC to act as an H-bridge such as the popular L293 IC, there may be times you may want to design one yourself for any To build an H-bridge, the only option is not to use an IC chip for an H-bridge. Therefore, the motor can be utilized with its full In this circuit, we will show how to build an H-bridge circuit with transistors.Īn h bridge is a circuit that is used primarily to control motors they allow for forward and reverse motion of the motors.
