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 senses a first AC signal at an output of the power conditioner and generates a second AC signal at the energy storage device. The second AC signal has a frequency substantially equal to a frequency of the first AC signal and a phase shift of about 45 degrees relative to a phase of the first AC signal.
