I try to simulate the Spike behavior of a Mosfet in a push pull converter(see the attach).
I use a Coss capacitor to simuate the Coss of a Mosfet, and a inductor to simuate the leaguage of a transformer.
The Coss and the inductor will introduce the spike of a Mosfet when it turns off.
But my circuit does give me this behavior.
Do I miss something? What should I do to simulate the Spike behavior of a Mosfet ?
The 600 V rating of your Level 2 switch is also defining an internal zener voltage. You are getting a spike but it is being capped by the zener. Increase your fet voltage rating and the spike will show up.
