H Bridge Motor. The basic operating mode of an h bridge is fairly simple. These circuits are often used in robotics and other applications to allow dc motors to run forwards or backwards.
If q1 and q4 are turned on the left lead of the motor will be connected to the power supply while the right lead is connected to ground. Most dc to ac converters most ac ac converters the dc to dc push pull converter isolated dc to dc converter most motor controllers and many other kinds of power electronics use h bridges.

The speed of the motor is proportional to the voltage and direction is dependent on the polarity direction of current. The most common use of an h bridge is to drive a dc motor allowing directional control. Four switches are connected in between ve supply and ground and dc motor is connected in between two switches as shown. The l293ne sn754410 is a very basic h bridge.
