Abstract:
1. A method for decreasing a voltage perturbation at an output of a single phase power converter in response to a load current perturbation in the single phase power converter at varying repetition rates of load transitions, comprising: providing the single phase power converter comprising: operating the single phase power converter to inhibit a load step rate and a switching frequency of the single phase power converter from matching for a significant period of time, wherein operating the single phase power converter includes dithering an output signal of the single phase power converter, and wherein operating the single phase power converter to inhibit a load step rate and a switching frequency from matching for a significant period of time includes programming the ramp signal generator to generate an output signal having a predetermined frequency and adjusting an output frequency of the single phase power converter so that a load step period and an on-time of the single phase power converter are in a changing temporal relationship.
