Abstract

This paper introduces an optimised design procedure for a DC–DC buck, boost and buck-boost configurations in a single circuit with an integrated dissipative snubber, aiming to enhance performance and efficiency. The conventional buck-boost converter’s versatility in adjusting the output voltage is complemented by a dissipative snubber, mitigating hard switching challenges in power semiconductors. Utilising advanced control techniques for seamless transitions between step-down and step-up modes, the proposed circuit ensures optimal operation across varying input voltages. The research delves into the snubber’s impact on limiting the maximum voltage stress across the switch, considering power losses in the snubber resistor. Simulation, analysis and experimental results validate the design’s effectiveness in meeting voltage regulation requirements, showcasing its adaptability to diverse electronic applications. This optimised design methodology holds promise for improving DC–DC converter efficiency in practical applications where mitigating switching losses and optimising voltage stress are critical considerations. Also this proposed converter provides output simultaneously for buck and boost configurations. The simulation and mathematical analysis are validated using the experimental prototype.

Abstract

In this letter, a reconfigured switched-capacitor converter (SCC) is proposed that is capable of achieving seven negative voltage conversion ratios (VCRs) using only three flying capacitors and minimum number of switches. The proposed converter is used to drive a white-LED backlight (WLB) in cellular phones for various backlight conditions. The negative VCR is realized with a single-input single-output structure using 10 CMOS switches and three flying capacitors. The reconfigured SCC has an advantage of choosing buck/boost voltages to drive the WLBs for various black light conditions. The proposed converter is tested experimentally with a low input voltage of 10 mV to 0.5 mV, and it maintains a high efficiency of 85%-95% with an output voltage that varies from −1 mV to −0.1 V.
