ABSTRACT:
A power transfer apparatus includes an impedance matching system coupled between a variable voltage source, e.g., a solar cell array, and a load. A parameter of the load indicative of the power being delivered to the load is sensed and the control signal thereby derived is employed to adjust the impedance matching system. The adjustment is such as to maximize the value of the parameter.
