An Impedance-Source-Based Soft-Switched High Step-Up DC–DC Converter With an Active Clamp

IEEE transactions on power electronics
This article proposes a high step-up dc–dc converter based on a trans-inverse impedance-source structure, in which the voltage gain of the converter is increased by using a lower number of turns ratio of the coupled inductors (CI) windings.

An Interleaved Active-Clamp Forward Converter Modified for Reduced Primary Conduction Loss Without Additional Components

IEEE transactions on power electronics, 2020
This paper proposes an interleaved active-clamp forward (IACF) converter modified for high efficiency without any additional component. To employ high input voltage, the components on one active-clamp forward module are re-arranged from the conventional ...

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

Active Neutral-Point-Clamped Multilevel Converters

IEEE 36th Conference on Power Electronics Specialists, 2005., 2006
This paper proposes a multilevel power conversion concept based on the combination of neutral-point-clamped (NPC) and floating capacitor converters. In the proposed scheme, the voltage balancing across the floating capacitors is achieved by using a proper selection of redundant switching states, and the neutral-point voltage is controlled by the ...

Dual Series-Resonant Active-Clamp Converter

IEEE Transactions on Industrial Electronics, 2008
A dual series-resonant active-clamp dc-dc converter is proposed to obtain high efficiency. The proposed converter employs an active-clamp technique, while a series-resonant scheme controls the output voltage with the complementary pulsewidth modulation controller. The active-clamp circuit serves to recycle the energy stored in the leakage inductance or
