Actively clamped bidirectional flyback converter

IEEE Transactions on Industrial Electronics, 2000
An actively clamped bidirectional flyback converter is proposed. The converter's operation is examined in detail. All switches in the converter have zero-voltage-switching characteristics. A low-frequency behavior model and small-signal transfer functions are derived. It is found that the flow of current is directly under the control of the duty cycle,

ESD robust high-voltage active clamps

Microelectronics Reliability, 2009
Using circuit simulation extended by a proper failure criterion, the HBM and TLP robustness of high-voltage clamps can be accurately predicted without the need for test silicon. Electrical measurements, physical damage analysis, and device simulation have proved that the drain junction breakdown voltage constitutes the proper failure criterion for our ...

The ZVS-PWM Active-Clamping CUK Converter

IEEE Transactions on Industrial Electronics, 2004
A CUK converter featuring clamping action, pulsewidth modulation, and soft-switching commutation is proposed to overcome the limitations of the conventional CUK converter. As the resonant circuits absorb almost all parasitic reactances of switches, including transistor output capacitances, this converter is suitable for high-frequency operation ...

A Multilevel Active-Clamped Converter Topology—Operating Principle

IEEE Transactions on Industrial Electronics, 2011
This paper presents a novel multilevel activeclamped converter topology, which is an extension to m levels of the three-level active neutral-point-clamped topology. The operating principle is established through the definition of a proper set of switching states and a transition strategy between adjacent switching states.

Active Clamp ZVT Boost Converter

2006 1ST IEEE Conference on Industrial Electronics and Applications, 2006
In this paper, the technique of active clamp is applied in ZVT boost converter and forms active clamp ZVT boost converter. This converter is not only simple in topology but also achieves ZVT in both the main switch and the auxilary switch. The boost diode turns off naturally and there is no reverse recovery loss.

Active-clamping dual resonant converter

2009 IEEE International Symposium on Industrial Electronics, 2009
A dual resonant converter using active clamp circuit is presented in this paper. The active clamp circuit is employed to limit the voltage stress and create zero-voltage-switching (ZVS) turn-on feature for power switches. Moreover, the dual resonant tanks are composed by the leakage inductors and resonant capacitors to achieve zero-current-switching ...

Lossless active clamp for secondary circuits

INTELEC - Twentieth International Telecommunications Energy Conference (Cat. No.98CH36263), 2002
Lossless snubbers have been developed with the emphasis on snubbing the primary side switches. With the switching losses in the primary being minimised, the secondary diode losses become a major limiting factor of converter operating frequency and total efficiency. To address this problem, a new active lossless clamp for secondary diodes of switch mode

Improved active clamp for secondary circuits

INTELEC. Twenty-Second International Telecommunications Energy Conference (Cat. No.00CH37131), 2002
The paper describes improvements to an active clamp for secondary circuits in isolated converter topologies. The active clamp provides both voltage clamping of the secondary diodes and the recycling of diode reverse recovery energy stored in the leakage inductance of the transformer secondary winding.

The Active Clamp Sepic- Flyback Converter

IEEE 36th Conference on Power Electronics Specialists, 2005., 2006
A high efficiency active clamp sepic-flyback converter is presented. The proposed converter is superposition of sepic converter mode and flyback converter mode. Not only sepic mode output but also flyback mode output can be fully regulated by constant frequency PWM control. Merging sepic and flyback topology can share the transformer, power MOSFET, and
