Abstract

PURPOSE: To achieve a power amplifier which is simple in constitution, low in distortion, and high in power efficiency, by supplying a power supply voltage accoring to the output voltage of an SEPP output stage to complementary type transistors constituting the SEPP output stage.
CONSTITUTION: When a signal from a signal source S is at a positive half cycle, one transistor (TR)1 of a pair of complementary type transistors cconstituting an SEPP output stage turns on and power is supplied to a load L, the output is applied also to a positive side amplifier 3, one end of a positive side cell 5 is driven with the output, and a power supply voltage applied to the collector for the TR1 from the cell 5 is increased according to the output voltage of the SEPP output stage. When the signal from the signal source S is at a negative half cycle, another TR2 turns on and similar operation is made to a negative side amplifier 4 and a cell 6.
