Abstract:
This paper presents a transformer less hybrid
series active filter (THSeAF) based PV system. The proposed
system to enhance the power quality in single-phase systems with
constant supply, which supports critical loads behaviors as highharmonic
impedance. In this method, deals with energy
management and power quality issues related to electric
transportation and focus on improving the electric vehicle load
connected to grid. This is based on the Power Factor Correction
(PFC) conversion with harmonic modulation technique that will
give betterment of power factor in PFC operation. The control
strategy was designed to prevention of current harmonic
distortions with the nonlinear loads to control the flow of utility
without any usual bulky and costly transformer. Power factor
along with AC side will also maintained to some value and also
eliminate the voltage distortions at the Common coupling point.
The proposed system protecting sensitive loads from voltage
distortions, swells and sags with respect to power system, without
the series transformer it is advantageous for an industrial
implementation. This paper carried out with 2-kVA power
demonstrating the effectiveness of the existing topology.
