Abstract:
This paper is aimed to propose an improved boost DC-DC converter, based on the idea of switched-capacitor and switched-boost converters. A modified version of the conventional switched-capacitor switched-boost converter is proposed, particularly suitable for high power applications. The major contributions concern the reduction of the stress in the power components as well as the voltage ripple reduction. Indeed, the current of the switches as well as the current of the diodes are reduced in the proposed converter. Nevertheless, the proposed idea slightly affects the boost factor of the converter. The performance of the proposed step-up DC-DC converter is evaluated through some simulations done in MATLAB.
