Abstract: A method is provided for minimizing a double-frequency ripple power exchanged between a load and an energy source, the energy source delivering electrical power to the load through a single-phase power conditioner, and the power conditioner being coupled to an energy storage device. The method includes determining a phase shift of an AC output signal of the power condition and an average AC output power of the power conditioner. The average AC output power may be a predetermined value or a calculated value based on sensed or measured signals. The method further includes generating an AC signal at an energy storage device. The generated AC signal has an amplitude that is a function of the average AC output power and a phase shift substantially equal to 45 degrees minus an amount that is dependent on the determined phase shift. In some embodiments, the phase shift may be determined to be of a non-zero value.
