I once spent a week chasing down oscillation that was simply the timestep aliasing on the switching period. SPICE can be a d.o.g (seriously, that's censored on this forum?) for these switching power supplies, so I'd say in your transient simulation command, add a max timestep well below your switching period and add 'uic' on the end of the line. Remember to include the ESR of the output cap and any load resistance. The pre-driver board is mainly composed by three parts: the power supply section, PWM driving portion and over-voltage protection section 2. This inverter is composed of three parts: pre-driver board, stage driver board and power board. Depending on circuits you can use a ready PWM ICs TL494 SG3524 or SG3525 or some digital switchmode regulator made it with some MCUs PIC or AVR. You can derive a linear model of the buck converter to stabilise it with equations in voltage sources etc and then when you add the transformer, add it in as a turns ratio in the equations, or you can derive a Bode plot of the plant by hand on paper with the equatrions, it's not complicated.

And yes, the proper way is shut down IR2110 at the same time. Ressmps, I'd advise getting a behavioral model of your secondary side working as a buck converter first with ideal opamps, switches, diodes and latches, then add the transformer, then add the isolation. The SMPS at the front page is the OLD version of the commercial design I made long time ago. Unfortunately, I can't load it from work anymore but, assuming its the right file, somewhere in there is a type III compensation design guide with a zener regulated secondary aux supply.
