Three-Phase, Four-Wire UPQC Topology with Reduced Switching Losses
نویسندگان
چکیده
The paper introduces the modified UPQC topology with reduced switching losses. UPQC is a versatile custom power device which consists of two inverters connected back to back and deals with both load current and supply voltage imperfections. It can simultaneously perform as shunt and series active power filters. The series part of the UPQC acts as Dynamic Voltage Restorer (DVR). It is used to maintain balanced, distortion free nominal voltage at the load. The shunt part of the UPQC acts as Distribution STATIC Compensator (DSTATCOM) and it is used to compensate load reactive power, harmonics and balance the load currents there by making the source current balanced and distortion free with unity power factor. The efficiency of the proposed configuration has been verified through simulation using MATLAB/SIMULINK
