| Abstract: | An high-power SCR Switching Power Amplifier（SPA）is introduced.Three kinds of working states of the circuit in different frequency are analyzed.The equivalent circuit models are developed when the SPA works in the natural commutation condition.A cycle analog switch with high efficiency and low resistance is in designed OrCAD,with which the equivalent circuit model in the natural commutation state is simulated.This method metioned can calculate the voltage and current at any point of the SPA.And the simulation data can truly reflect the working situation of the system,which has a certain reference value. |
