Abstract :
This paper presents a design, mathematical modeling, simulation results and laboratory implementation of a 300 W high gain dc-dc boost converter with a coupled inductor, to step up the 24 V of a battery bank to 311 Vdc, aiming to supply residential loads with dc voltage in an off-grid PV system. The converter can supply most of the residential ac loads which input stage is a single-phase rectifier. Laboratory tests with the 300 W converter supplying electronic lights, mobile charger and audio-video system ac showed the viability of the proposed idea.
