I have design question and I'm wondering which option is the better choice.
So I'm taking 48V battery bank and feeding it to an H-bridge IGBT module thats being driven by a gate driver. Once the waveform comes out of the IGBT module it'll be resemble a Vac waveform. Up until now I thought I was just going to put it into a transformer and do my low pass filtering on the output side before the rectification circuit.
The more I read and try to wrap my head around the best practice, I'm re-considering my design and want to use a low pass filter prior to the transformer instead of after.
I've uploaded a simple flow chart of my two considerations.
Option A is lowpass after
Option B is lowpass before
Thanks for the help,
double
