Hello. I have to desing and build for my last semester an active harmonic filter. I have desinged it in simulation and now I'm trying to make what happen in simulation real. So here is the problem. Basically many problems. I 've managed to build the control circuit. The basic concept is this: A current sensor gives me the current. This current brings odd harmonics and 50 Hz. So I am using a 50Hz band stop filter so that the output of the filter will be the Ireference for the inverter. The inverter has to create this Iref and put it back to the line before the load. This isn't very simple. I have only two months and I don't know If I'm going to make it. So I need your help, if someone of you knows anything about harmonic filters, or if how to built them, or how can i built the inverter. Any help will be appreciated. Thank you. Sorry for my poor English.
