A comparative study between the topologies consisting of the Conventional Electronic Load Controller and the Proposed Electronic Load controller (ELC)has been carried out in this paper for the power Quality Improvement in a conventional Electronic Load controller used for Isolated pico-hydropower generation using Asynchronous generator (AG). A polygon wound autotransformer with reduced KiloVolts ampere rating is employed in the proposed ELC for reducing the harmonic current reduction inorder to meet the power quality requirements as prescribed by IEEE standard-519. The conventional ELC employs six-pulse-bridge-rectifier and the Proposed ELC employs twenty four -pulse-bridge-rectifier. The study is carried out in MATLAB using SIMULINK and power system blockset toolboxes. Experimental validation is carried out for both ELCs for regulating the voltage and frequency of an isolated Asynchronous generator driven by uncontrolled pico-hydroturbine.
