Full bridge converter drive

We consider here permanent magnet DC motors where the stator is composed of two or more permanent-magnet pole pieces and the rotor is composed of windings that are connected to a mechanical commutator.
The full-bridge converter drive consists of four power switches that are used to adjust the motor voltage and polarity using pulse width modulation (PWM). The current can thus be controlled to flow in either direction through the motor windings, allowing the motor to run in both directions.
