Hello,

When I use the model pspice for the IR2110 for a full bridge I got overflow error. Does someone have a solution to this problem ?

I tried a lot of tweak with the solver, try to use initial condition on various capacitor... But no found solution !

Thanks a lot !

Regards.

Hi,

I am recommending you few steps and try whether it works or not.

1) Remove load and check the output  voltage.

2) Since, two half bride are connected parallel across DC bus, try to remove one and check the pulse output.

3) If these don't work then there might be a issue with your time signals ( either delay or any other timing signal) .

Hi,

You can provide an initial value to the bootstrap capacitors C17, C23 and check if the error is resolved.

Thanks.

What is the deadtime between HIN and LIN? Try with a delay between the two and with 50% duty cycle, LIN first and then HIN.
Try removing the RC across the MOSFETs and the RC at the load L.
