This is same as three phase shunt active power filter. It takes single phase load voltage and current as input and generates signal for other two phase by delay block (delay of 1/150 second which is 2*pi/3 lag for 50Hz system). Then it calculates compensating current but injects the current of 1st phase only.

Hi Niranjan. Your simulation is really awesome. I have recently started studying the SAPFs. I was under the impression that the DC link's voltage in Shunt active filter is supplied through a (rectifier+boost) circuit that is connected to the gird. However, it appears that in your simulation and many others, the DC link capacitors are activelye charged through the bridge switches' connection to the grid. I would really appreciate if you could explain to me how the active charging of Capcitor works while mentaining the control of inverter through Hysteresis controller. It means the world to me. Please feel free to email me:
