ANALYSIS AND IMPACT OF ELECTRIC VEHICLE CHARGING STATION ON POWER QUALITY

Abstract

An advanced bridgeless(BL) Cuk motor grounded EV( Electric Vehicle) battery bowl with high power
factor( PF) and increased effectiveness, is designed and developed in this work. It provides low cost and high power
viscosity grounded charging result for EV. This bowl incorporates lower number of bias operating over one
switching cycle, which reduces the fresh conduction loss incurred by a diode ground therapy of conventional bowl.
Hence, it improves the bowl effectiveness. The added advantage of proposed topology is that the unwanted
capacitive coupling circle is removed, as well as unwanted conduction through the body diode of inactive switch in
preliminarily developed BL Cuk motor is avoided. This significantly improves the bowl effectiveness. For the
constant current( CC) and constant voltage( CV) charging, the commands, are accompanied by a flyback motor. The
proposed bowl draws a sinusoidal current from AC mains along with the total harmonious deformation( THD) in
force current is reduced to the limits specified by the IEC 61000-3-2 guidelines. The bettered effectiveness and PQ
indicators of proposed bowl, are delved to demonstrate its satisfactory charging operation at all operating
conditions.
