Hello,
I have a question about LCL filter for active front end. I was wondering what the advangate is connecting capacitors in such a filter in Y configuration instead of delta. It seems I cannot find a reason why Y connection is better than delta. Connecting caps in delta results in smaller current through the caps. Also, delta configuration will reduce the amount of capacitance by a factor of 3 compared to Y.
On the other hand, some manufacturers seem prefer to use Y connection instead of delta. Can someone explain? Thanks
