I am actually simulating a single phase transformerless grid connected PV inverter with unipolar modulation. I have simulated and I found that the CM voltage has a lot of high frequency components and high amount of CM leakage current. I am working on how to reduce this high frequency components in CM voltage and to reduce the CM leakage current ? For this I need to design a suitable filter for it. Can we design an EMI (Electromagnetic Interference) filter for this ? If yes then how to design and simulate in matlab/simulink, how to calculate the value of inductances and capacitances of the EMI filter ?
For the calculation of the values of inductances and capacitances of the EMI filter, pls check the below paper and book:
