Hi

I need to build an analog controlled single phase inverter as quick as possible to test some ideas for my PHD. I will use a SEMIKRON IGBT bridge for the power stage.

I would like to implement an unipolar SPWM modulation. However, I was taking a look at some manufacturer's websites and I couldn't find any integrated chip to implement a SPWM in a straighforward way.

I would like to know if there is any commercial chip that allows implementing this kind of modulation, such as UC3823 for DC-DC converters. The idea is to avoid implementing the triangular signal generator, the comparators, dead times, etc.. in separate ways.

Thank you in advance.
