Abstract
A high-efficiency low-distortion parallel amplifier or regulator is driven by an input signal source V.sub.i. An input signal passes to a linear circuit LC, and the output current i.sub.1 from the linear circuit passes to the input of a switching circuit SC. Alternatively, the input to the switching circuit may be any other signal that is a function of the linear-circuit output current. The output of the switching circuit passes through a coupling network CN and is applied with the output current of the linear circuit to a load impedance ZL. The output of the switching circuit acts to reduce the output current of the linear circuit so that the power it supplies is low. A low linear-circuit output current is usually sufficient to drive the switching circuit and coupling network to the maximum current required by the load. The system automatically adjusts independently of the load impedence so that with high output current most of the current is supplied by the switching circuit.
