In this paper, a novel DC-DC converter topology that provides very high gain at high power rating is presented. The proposed DC-DC converter is obtained by combining interleaved boost converter (IBC), coupled inductor and switched capacitor. Voltage gain expression and design equations of the proposed converter are derived. The operational modes, characteristic waveforms and the design details of the 60V/6.6kV, 3kW DC-DC converter are also presented. Results obtained from simulation prove that the converter is capable of providing a very high voltage gain of 100 at high power rating of 3kW. Based on the proposed design and simulation results, it is observed that the voltage and current stress of the main switch is within acceptable limits. Thus, the proposed converter promises to be a suitable alternative to existing topologies in DC microgrid applications. © 2013 IEEE.

Analysis and design of ultra-high step up converter for DC microgrids

2013 Annual IEEE India Conference (INDICON)

The sustainable energy resources, namely PV, wind, fuel chambers or vitality stowage strategies like ultra-capacitors or battery management, produce output voltage at the limit of about 12–70 VDC. The grid can be connected to the energy sources whose voltage level can be altered depending on the electrical standards. As the first step, AC mains voltage requirement should be fulfilled, to attain this boost-up of voltage up to adequate level where the DC to AC conversion is attained to balance the utility rating. The another challenge in this energy generation is maintaining efficiency, and this efficiency is affected at the step-up process of DC to DC conversion. This manuscript is intensive on high efficiency and advanced topologies of boost-up mode DC to DC converters with increased voltage ratio. The difference depends on the existence or absence of transformer nodes. And also a new topology of DC to DC converter is implemented, and it is designed using MATLAB/Simulink. A droop control strategy is used to parallel two converters in load-sharing point. © Springer Nature Singapore Pte Ltd. 2018.

Topologies of a DC–DC Converter for Micro-grid Application and Implementation of Parallel Quadratic Boost Converter

This study proposes a novel non-isolated high-gain high-power DC-DC converter. The converter is developed from a basic high-gain high-power converter structure. The proposed converter comprises of a three-phase interleaved boost converter, one coupled inductor and a voltage multiplier cell which act as gain extension stage. The main desirable features like voltage gain, stress on the switches and diodes, turns ratio, component utilisation factor and efficiency are summarised. The power circuit, operational details, simulation and experimental results of the 60 V/1.1 kV, 3 kW, 100 kHz proposed converter are presented. © The Institution of Engineering and Technology 2016.
