A method and system to improve efficiency and performance of a power supply by providing a consistent voltage level into a multiple-pole circuit breaker (10) to improve efficiency, reduce heat generation and increase the speed and consistency of "turn-on" times. A power supply (14) for changing waveform comprises circuitry for receiving at least one waveform having first and second components. Circuitry is provided for changing the first component and means for outputting a waveform comprising the outputs from the changing circuitry are also provided.
