Abstract
A step-up DC-DC converter is proposed by inserting a new switched-capacitor cell in a modified PWM boost circuit. The obtained hybrid PWM non-isolated converter is able to provide a large DC gain, as necessary for serving as front-end to electrical grids supplied by solar or fuel cells. It features low voltage stress on the switches compared with traditional boost converter, allowing for the use of low-voltage rated components, with smaller nominal parasitic on-resistances. Analysis, simulation and experimental data show the superiority of the proposed converter over other hybrid converters in a trade-off of complexity, components count, voltage ratio and voltage stress on the switches.
