Total Harmonic reduction is a present day
scenario where the demand and supply needs to full fill
with much efficiency. The demand for the power
electronic devices for the power quality created a supply
with maximum harmonic reduction as the applications
are being increased in day by day world. The charging
station for the electric cars needed much less harmonics
as it needs to convert DC to charge the batteries.
Different types of filters are implemented but these
filters have more stress on the architectural point and
increase the overall cost of the station. A shunt filter
along with PI controller is implemented in this paper.
The shunt hybrid filter is applied for high power
applications with 48 pulse AC/DC converter. The 48
pulse converter is implemented with the combination of
the eight six pulse rectifier in parallel and are connected
with four three phase transformers. The phase shift for
different transformers is achieved by using star delta
connection. The main focus of this article is to decrease
the Harmonics like 3rd,5th,7th and 13th . This is more
economical than any other alternate rectifier and will be
concisely explained and verified and simulated in Matlab
