What Is Dynamic Braking and How Does It Work?

WebDynamic Braking Application Summary Dynamic braking is one method used to dissipate excess energy generated when the load controlled by an adjustable frequency drive (AFD) is quickly slowed or stopped. When a motor is quickly slowed down, it becomes a generator, feeding energy back into the AFD. The energy that is fed back increases the DC WebJan 26, 2013 · If you are driving a motor with a half-bridge or H-bridge and PWM or similar, you have regenerative braking. Let's consider a half-bridge, since for this analysis we will run the motor in only one direction: First, let's consider non-regenerative braking. If the bridge output is high (S1 closed, S2 open), the motor will accelerate to full speed.
