A method of reducing switching losses in a power supply includes the steps of advancing the output voltage of a first pole of a power cell by a first angle, retarding the output voltage of a second pole of the power cell by a second angle, and producing a combined output voltage of the power cell equal to a positive pulse of a duration angle equal to the sum of the first angle and the second angle for a first half of a switching cycle of the power cell, and equal to a negative pulse of a duration angle equal to the sum of the first angle and the second angle for a second half of the switching cycle of the power cell.
