Abstract

The main cause of inferior quality power supply involves the disturbance of power distribution to the consumers, who are prone to use low and high voltage current for their appliances, devices and gadgets. This perception of power quality has led to the advent of modern custom power devices for power quality improvement Unified Power quality Conditioner (UPQC) are a class of custom power devices for providing reliable distribution power quality. They employ voltage fed type of converters for both the active and reactive power compensation. There are many transformerless topologies available in literature such as H4, H5, H6, HERCC (Highly Efficient and Reliable Converters Concept) etc. Transformerless Hybrid Series Active Filter (THSeAF) is modelled and the control strategies for the THSeAF incorporating the renewable energy resources are designed in order to enhance the power quality. The THSeAF converter scheme has adopted a P+R topology in which the common mode leakage current is minimal. A prototype of THSeAF to validate the proposed control strategy is developed which validates the results with simulation.
