Complementary symmetry push-pull circuit

Posted on Mar 28, 2007

Class A power amplifier distortion, although low, but its low efficiency and output power is small, so people designed B power amplifier circuit. B amplifier circuit is to work

from the middle point Q moves down to the position Q2, that is static -free base of the transistor bias, b 00 only when the input signal is the role of the transistor is turned on before work. It works when the maximum collector current of the magnitude of the current class Bijia much larger output. But it is only in the positive half cycle of the signal t is not a negative half-cycle work. This causes serious distortion of the output signal o this end, the B push-pull amplifier circuit uses the output of work, consisting of two alternating work tube output, l-140 one of the circuit shown by the NPN transistor VTz and a PNP tube VT3 composition. In the positive half cycle signal VT. 3 work, negative half cycle of the signal VT2 tube in two output tubes, respectively, the output signal of the positive and negative half-cycle, the last in a complete synthesis of the total output of the output signal of the circuit o taken with two different polarities its lack of complementary transistors, so this circuit is called complementary symmetry push-pull output path.
