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 high-voltage-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.
