Analysis and design of bipolar Dickson DC-DC converter

This paper presents a novel converter based on the Dickson voltage multiplier for high voltage applications. This converter will have two Dickson chains connected differently to improve the original Dickson voltage multiplier. The main advantage of this converter is that the stresses on the capacitor will be reduced by half, and the output voltage ripples are reduced. The required energy storage of the capacitor is 30% of the original Dickson voltage switched capacitor converter. The analysis and design of this converter are presented and verified by simulation. A 20W prototype was implemented to validate the analysis and simulation. The results show that the proposed converter is an improved version of the original Dickson and modified Dickson converters and it has higher efficiency up to 94%.
