H bridge circuit


Posted on Feb 5, 2014

An H bridge is a kind of circuit you use to control the direction (and sometimes speed) of an electric motor, using only a single polarity voltage (you need to reverse the way current flows in order to reverse the way the motor rolls). You have 4 transistors, wired as ON OFF switches. Two signal lines allow you to run the motor in one direction, w

hen reversed, the motor runs in the other direction. It`s very straightforward to use and build, but be careful to use only small motors, as the currents drawn from the bigger types can burn your components. All circuits included here are recommended to be assembled in printed circuit boards. Printed circuit boards, or PCB`s increase the circuit reliability and mechanical stability.
