These days, the most common drive in businesses is the Variable Frequency Drive (VFD). However, when
dynamic braking is employed in the typical VFD, some energy is lost in it. When a motor functions as a generator,
there are several ways to use and convert the regenerated energy so that it may be stored instead of evaporating as heat
during dynamic braking. This paper illustrates some of the approaches.
