Power Quality Improved Single-Stage Single-Switch Boost-Boost Power Converter With Wide Conversion Range

Abstract

DC system have a lot of field application such as Railway, Industry, Commerce and Scientific Applications. To supply this DC energy from the consisting AC system use of Electronic equipments are common. This causes a lot of power quality problems such as Total harmonic distortion (THD) and poor power factor to the supply system. Instead of this it also affect the revenue of the Energy companies in form of energy loss and causes the unnecessary economic impact along with system instabilities. So to improve power quality a single-stage single- switch Boost-Boost power converter with the Average Mode Control Scheme (AMCS) is presented in this paper to provide DC power output. This converter provides 3.90% THD which is 0.20% improved than a single-stage single-switch boost converter [20] at 500W and as per the IEEE standard. Instead of this improvement, converter also widen their fidelity with the further THD alleviation on the increased Reactive power demand. The converter is proposed on the MATLAB/ SIMULINK platform and the waveforms are shown here.
