Abstract:
A dynamic braking system for an electric power system includes a switching device coupled to an electrical conductor. The switching device is configured to open and close with a plurality of predetermined frequencies. The dynamic braking system also includes an inductive device coupled to the switching device. The power losses of the inductive device are at least partially a function of the plurality of predetermined frequencies. The dynamic braking system further includes a dynamic braking controller coupled to the switching device. The dynamic braking controller is configured to open and close the switching device with at least one of the predetermined frequencies to dissipate electric power from the electrical conductor at a predetermined rate by regulating the power losses of the inductive device as a function of the predetermined frequencies.
