介绍了一种甚低频可控硅开关功率放大器,建立了其在临界换流状态时的等效电路模型和非线性数学模型,在OrCAD环境下仿真了等效电路模型,并采用拉氏变换法和微分方程数值分析法求解其非线性数学模型。三种方法都能计算出功放任意点的电流电压值,且结果相符。

An VLF SCR Switching Power Amplifier（SPA） is introduced.Three equivalent circuit models and one nonlinear maths model are developed when the SPA works in critical commutating condition.The circuit models are emulated in OrCAD,and the nonlinear maths model is solved with Laplace transform method and numerical analysis method respectively.All the methods metioned can calculate the voltage and current at any point of the SPA,from which the results are accordant.
