Boost converter with bipolar Dickson voltage multiplier cells

This paper presents the analysis and design of a boost converter with bipolar Dickson voltage multiplier. The bipolar Dickson voltage multiplier offers high gain with low stress on both capacitors and switches. Connecting bipolar Dickson cell to a boost converter yields several benefits such as an overall high static voltage gain and at the same time reduces the required inductance that ensures operation in continuous conduction mode. The proposed converter is suitable for interfacing renewable energy sources because it has non-pulsating input current. The proposed converter was simulated to convert 20 V to 200 V. A 50 W hardware prototype was implemented using GaN active switches to validate the simulation and theory.
