Abstract
To improve the error oscillation which happened in inductive load using pspice soft to simulate the circuit
according to the semiconductor internal principle
through solving diode based ambipolar diffusion equations
a high-power PIN diode model for PSPICE sub-circuit was put forward.In the model
the diode forward conduction and reverse recovery characteristics were taken into account.The simulation waves of reverse voltage and current was obtained through the test circuit
