On the reliability of DC-DC power converters
Collection of Technical Papers. 35th Intersociety Energy Conversion Engineering Conference and Exhibit (IECEC) (Cat. No.00CH37022), 2000This paper presents the results obtained from a study conducted to evaluate the long-term operational reliability of DC-DC power converters used in computer applications. A full-bridge, phase-shifted zero voltage switching (ZVS) PWM converter was investigated experimentally and theoretically.

DC-DC Buck Converter for Supercapacitor
2019 International Conference on Electronics, Information, and Communication (ICEIC), 2019In this paper, a DCM DC-DC buck converter for charging supercapacitor is proposed. The buck converter consists of compensator for gain and frequency compensation, pulsewidth modulation(PWM) control logic for switch control, clock generator, and soft start-up to reduce the inrush current of an inductor during the initial operation of the converter.

These days, on account of the immense advances in energy technology, sustainable power source has developed and turned into an essential part of the power system. However, the output energy that is collected from the natural surrounding elements is unstable, therefore this paper presents a DC-DC Buck-Boost Converter to control and manage the Energy ...

Comparison of conventional dc-dc converter and a family of diode-assisted dc-dc converter
Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012In the conventional dc-dc converter, two sets of diode and adjacent passive component connected in X-shape can be applied to enhance voltage boost or buck capability, which is more suitable for high step-up or high step-down power conversion. This paper mainly investigates and compares conventional dc-dc converters and a family of diode-assisted dc-dc ...

Switched-capacitorized DC/DC converters
2009 4th IEEE Conference on Industrial Electronics and Applications, 2009Switched capacitor DC/DC converters are new prototype of DC/DC conversion technology. Since switched capacitor can be integrated into a power IC chip, consequently, these converters have small size and high power density. Switched capacitor can be used in voltage-lift technique to construct DC/DC converters.

Dual-bridge DC-DC converter: a new topology of no deadtime DC-DC converters
APEC. Seventeenth Annual IEEE Applied Power Electronics Conference and Exposition (Cat. No.02CH37335), 2003Two new topologies characterized by no deadtime and small valued output inductor, the dual-bridge DC-DC converter and the dual-bridge converter with ZVS, are presented and analyzed. Simple self-driven synchronous rectification can be used in the new topology for high efficiency implementation.

Operation principles of both inductor-based and switched-capacitor DC-DC converters are introduced in this chapter. Different aspects of these two types of DC-DC converters are investigated and compared. In particular, benefits and design obstacles of the time-interleaving multiphase topology are reviewed and discussed.
