UCC21530: Inverter output problem with Sine PWM technique using TINA TI

Hi,

Thank you for your question. I work on the applications team in the high power drivers group.

I get convergence errors when I try to simulate the circuit on my computer. Can you please post some screenshots of the inverter output, and describe why you think it is strange? We need your help to understand what you are seeing, and then we can walk through it together when we are on the same page.

Thanks and best regards,

John

sir,

i am attaching the circuit file and some screen shots of the figures.please go through them.

A quick reply is appreciable.

thank you.

i guess problem is not with the gate driver.

i am getting desired outputs from the gate driver.

i think problem is at the inverter side.

thank you
