Power system comprises of threenatural / physical characteristics namely voltage,current and frequency. Deviation in these physicalcharacteristics are termed as power quality issues inpower system. Presence of nonlinear current ornonlinear/unbalanced voltages and frequencies aretermed as power quality issue. These (current, voltageand frequencies) deviations result in failure/damageof equipment in power system. Power electronicconverters associated with their nonlinear switchingcharacteristics and high frequency operation are themajor cause for power quality issues. In order toreduce harmonics and improve power quality, HybridActive Power Filter (HAPF) or shunt HAPF can beemployed. The power improvement can be done usingvarious algorithm like RLS algorithm, DC link voltagecontroller, fuzzy logic based hybrid filter.
