A novel high voltage-boosting converter with active clamp
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015In this study, a high voltage-boosting converter is presented, which combines a coupled inductor, a charge pump capacitor, and active clamp circuit, so as to boost up the output voltage as well as to make the main switch turned on with zero voltage switching. In this converter, the coupled inductor behaves as not only an inductor but also a transformer.

Analysis of the Fault-Tolerance Capacity of the Multilevel Active-Clamped Converter
IEEE Transactions on Industrial Electronics, 2013Thanks to the inherent redundancy to generate the different output voltage levels, the multilevel active-clamped (MAC) topology presents an important fault-tolerance ability which makes it interesting for several applications. This paper presents an analysis of the fault-tolerance capacity of the MAC converter.

Designing HV active clamps for HBM robustness
2007 29th Electrical Overstress/Electrostatic Discharge Symposium (EOS/ESD), 2007Electrical measurements, physical damage analysis, and device simulation have proved that the drain junction breakdown voltage is the determining failure criterion for our HV active clamps. Using this criterion, the HBM and TLP robustness of such clamps can be accurately predicted by circuit simulation without the need for test silicon.

Ultrahigh step-down converter with active clamp
2017 IEEE 3rd International Future Energy Electronics Conference and ECCE Asia (IFEEC 2017 - ECCE Asia), 2017In this paper, the ultrahigh step-down converter with an active clamp circuit is proposed. With the active clamp circuit, the voltage spike across the central-tapped switch can be suppressed. The switches can achieve zero-voltage-switching (ZVS) turn-on or zero-current-switching (ZCS) turn-off. Finally, theoretical analysis and experimental results are

Active Clamp Converter with Full Resonant Switching
INTELEC 06 - Twenty-Eighth International Telecommunications Energy Conference, 2006The active clamp dc-dc converter topology efficiently resets the flux in the power transformer with an active switch and a clamp capacitor and provides low peak-inverse voltage for the output rectifiers over a wide operating range of input voltage. But like other isolated power conversion topologies, this topology loses zero-voltage switching (ZVS) for

Active Clamped Resonant Flyback with a Synchronous Rectifier
2011A zero-voltage-switching (ZVS) resonant flyback converter with a synchronous rectifier is presented in this paper. An active clamp circuit is added to the conventional flyback converter to clamp the voltage across the switches and provide ZVS operation.
