Non-Isolated High Step-Up DC/DC Converter With Coupled Inductor and Switched Capacitor

Novel High Step-Up DC-DC Converter With Coupled-Inductor and Switched-Capacitor Techniques

A novel high step-up DC-DC converter with coupled-inductor and switched-capacitor techniques is proposed in this paper. The capacitors are charged in parallel and are discharged in series by the coupled inductor, stacking on the output capacitor. Thus, the proposed converter can achieve high step-up voltage gain with appropriate duty ratio. Besides, the voltage spike on the main switch can be c...

DC-DC Step-Up Converter using Switched Coupled Inductor

A closed-loop high-gain switched-coupled-inductor switched-capacitor (SCISC) converter is proposed by combining a sawtooth wave generator, pulse-widthmodulation based (PWM based) compensator and nonoverlapping circuit for step-up DC-DC conversion and regulation. The power part between source VS and output VO contains two sub-circuits: (i) a switched-coupled-inductor (SCI) booster circuit, and (...

High Step up Switched Capacitor Inductor DC- DC Converter for UPS System with Renewable Energy Source

A new converter using a switched-inductor cell integrated with a switched-capacitor cell within a boost-like structure is proposed. The converter can achieve a very high dc conversion ratio. It can serve as the front-end dc-dc converter for a fuel cell in a UPS system. The inductors and capacitors are switched in a parallel-series configuration. The charging circuit of the inductors from the so...

Novel High Step-Up DC-DC Converter with Coupled-Inductor and Switched-Capacitor Technique for Sustainable Energy System

In this paper, a novel high step-up DC-DC converter is proposed for sustainable energy system. The proposed converter uses coupled inductor and switched-capacitor technique. The capacitors are charged in parallel and are discharged in series by the coupled-inductor to achieve high stepup voltage gain with appropriate duty ratio. Besides, the voltage stress on the main switch are reduced with a ...
