The picture shows the class B amplification complementary symmetry working principle circuit. (1)Its working principle. Static: IB=0, IC=0, uo=0 Dynamic: When it is in the ui's positive half cycle, the NPN transistor is in the mode of amplification and the PNP transistor is cloced. The current through RL is iC1. When it is in the ui's negative half cycle, the PNP transistor is in the mode of amplification and the NPN transistor is cloced. The current through RL is iC2.
