Abstract: A method for regulating a power conditioner output voltage level includes monitoring a first voltage level of a first supply source and a second voltage level of a second supply source and, while the power conditioner is being supplied by the first supply source, controlling a duty-cycle of an output switch of the power conditioner with feedback-based control signals generated based on errors between a target voltage level and samples of the output voltage level obtained at an output voltage sampling frequency.
