Hi All,

I am currently working on my senior project for which I require to design an inverter. I am using SPWM to drive an H-Bridge and I am generating the SPWM waveform using a PSoC 5lp. I understand that when using micro controllers, I need to use a MOSFET driver for which I am using an IR2110. I am currently trying to set up the PSPICE model, however, it is not working as it is not outputting anything. Is there anything that seems to be wrong?

I have attached the circuit to this post.

Thanks

Check the connections to the right-hand IR2110.
You are missing a boost diode from the + supply to the VB pin.
