A Novel Non-Isolated High-Gain DC-DC Boost Converter
In this paper, a novel interleaved boost converter topology is introduced. The proposed converter is based on a combination of two types of voltage multiplier cells (VMC): Dickson and Cockroft-Walton (CW) voltage multiplier. Connecting VMCs to an interleaved boost stage yields many benefits, including smaller ripples on the input current, reduced voltage stress across switches and capacitors, and high overall voltage gain. These advantages allow designers to design high gain dc-dc converters with low-rated and highly efficient semiconductor components. Moreover, the use of VMC can reduce the requirements of the required energy storage and also allow to design with smaller capacitors than the conventional boost converter. This paper presents the analysis of steady state voltage gain, the design of the converter, selection of the components, and simulation of the voltage and current stresses across switches and storage elements. Also, A 200 W prototype was implemented to convert 20 to 400 Vdc. The implementation details and major waveforms are included and illustrated.
