Abstract

In this paper a power line conditioner using a cascaded multilevel inverter based shunt active filter using synchronous reference frame (SRF) controller is developed to improve the power quality in the distribution system . The cascaded multilevel inverter consists of two H - bridges in which each bridge has separate dc source. Gati ng signals to the cascaded multilevel voltage source inverter are generated from proposed triangular - carrier current controller. Here control strategy is different from conventional methods and provides superior performance. Using Reference Frame Transform ation, the current is transformed from a ? b ? c stationery frame to rotating 0 ? d ? q frame. Using the PI controller, the current in the 0 ? d ? q frame is controlled to get the desired reference signal. This proposed cascaded five level active power fil ter system is validated through MATLAB/SIMULINK Platform. From simulation results observed that the cascaded multilevel inverter based shunt active filter effectively compensates the current harmonics
