I’m investigating transient switch arcing that occurs in a 3 phase switching unit.
I am planning on generating the phase signals with an STM32F4 using DAC and DMA with timing separation for the phase difference.
I need to boost this signal to around 40 V peak with around 3-5A with the ability to provide or than that for short periods.
I was considering a power opamp like the LM675 but I’m not sure if this would be the best or feasible approach.
Is there a typical way of accomplishing this kind of amplification?
I can purchase basic components as required and have lab bench power supplies available.
