ACCOMPLISHMENT OF VOLTAGE MULTIPLIER FOR HIGH VOLTAGE EFFICIENCY DC TO DC CONVERTER BASED ON DICKSON CHARGE PUMP

Abstract

DC distribution systems have gained popularity recently as they offer better
efficiency, higher reliability and low cost as compared to ac distribution systems.
They help in easier integration of renewable energy and its storage systems. But
the main challenge faced by such dc distribution systems is the use of power
electronic converters for integrating renewable sources into the dc bus. So a highvoltage-
gain dc-dc converter is introduced in this paper. The converter consists of a
two-phase interleaved boost converter on its input side and a Dickson charge pump
based voltage multiplier on its output side so that it provides an output voltage of
400 V for an input voltage as low as 20V.The voltage multiplier circuit associated
with the converter offers low voltage across the capacitors which potentially leads
to reduction in size. The converter can be fed to a three phase induction motor so
that analysis can be done efficiently and its simulation results are obtained using
MATLAB/ Simulink.
