Pspice convergance problem

[Hussainkh]

Dear all,

I am trying to use IR2127 as a gate driver for a Si MOSFET, but it doesn't work. When I tested gate driver circuit alone, it did work. However, when I connect the MOSFET into it, I got a problem which is attached with this post (convergence problem). I appreciate you in advance if you will be able to help me to solve this problem.

Short-circuiting the Mosfet would not help much to prevent simulation errors, particularly if the MOSFET model is not likely to trustworthy represent the parameters of the real-world device. You are also not providing any gate resistence as would be expected at an authentic circuit.

I would recomend you start by using some working curcuit/topology available on the web.

your shorting a voltage source?...maybe you have to put internal resistance in the voltage source to get it to work.
