Abstract
A power converter and controller system for a motor using an inductive load, such as a switched reluctance motor, which provides enhanced motor performance. The improved power converter and controller system accomplishes this by using a return bus having a storage device for storing energy. A controller monitors both the in the inductive load and the energy stored in the storage device and dynamically controls the storage device and the inductive load to dynamically control the current in the inductive load and the voltage on the storage device.
