Abstract

A new step-up basic switching cell formed by three passive elements and two diodes is proposed. It is inserted in a boost converter in order to obtain a new hybrid PWM nonisolated converter able to provide a large dc gain, as required in electrical grids supplied by solar or fuel cells. A family of converters can be created by inserting the defined switching structure in any step-up converter. Analysis, simulation and experimental data show the superiority of the proposed converter over other hybrid converters with similar complexity and the same voltage ratio: less voltage stresses on the switches.
