A new stacked step-up converter

A new step-up converter with one active switch and two diodes is proposed. Static properties are derived after a dc analysis and then components stresses and ripples are evaluated and design procedures are provided. The theoretical concepts are confirmed by simulation. Finally, a prototype is built and the experimental results confirmed the feasibility of the new topology. The new proposed converter exhibits higher step up conversion compared to the classical boost. Moreover, in the same application, semiconductor voltage stresses are lower for the new converter compared to the classical one, while semiconductor current stresses are the same.
