ABSTRACT:
A power transfer apparatus transfers electrical energy from a DC voltage source that may vary in potential, e.g., a solar cell array, to a load such as a DC motor connected to drive an AC motor-generator. A power transfer device couples the solar cells to the DC motor for driving the DC motor at a power level consistent with the power available from the array of solar cells. The AC motor is continuously connected to an AC line to be driven by conventional AC power. The DC motor, when operating, reduces the load on the AC motor and thereby reduces the AC power drawn or in some cases, causes the generator driven by the DC motor to return power to the AC line.
