A Novel Noncomplementary Active Clamp Flyback Control Technique

2019 IEEE Applied Power Electronics Conference and Exposition (APEC), 2019
This paper proposes an innovative non-complementary control method for an active clamp flyback converter. The proposed method recovers the leakage inductance energy and achieves soft switching for all the switches, while obtaining a lower RMS current compared to previous complementary or noncomplementary active clamp flyback control methods.

Interleaved PWM active-clamping buck-type converter

The 2010 International Power Electronics Conference - ECCE ASIA -, 2010
An interleaved pulse-width modulation (PWM) zero voltage switching (ZVS) converter is presented in this paper. Two converter modules with interleaved PWM scheme are used in the proposed circuit to achieve load current sharing and reduce the ripple currents on the input and output capacitors such that the size of the output choke and capacitor are ...

Ultrahigh step-down converter with active clamp

2017 IEEE 3rd International Future Energy Electronics Conference and ECCE Asia (IFEEC 2017 - ECCE Asia), 2017
In 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

Designing HV active clamps for HBM robustness

2007 29th Electrical Overstress/Electrostatic Discharge Symposium (EOS/ESD), 2007
Electrical 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.

Analysis of an Active-Clamp Flyback Converter

2020 IEEE International Conference on Consumer Electronics - Taiwan (ICCE-Taiwan), 2020
This study explored the operation principles of active clamp flyback converters. A control strategy was adopted to achieve strong noise immunity, and a voltage mode was configured to attain advantages such as simple circuit design. Experiments were performed to verify the feasibility of the proposed active clamp circuit.

Averaged switch modeling of active-clamped converters

IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.37243), 2002
In this paper, averaged switch modeling is applied to predict the dynamic behavior of converters with active voltage clamp. The procedure for deriving a large-signal averaged model, starting from defining the switch network and its waveforms, is described. As an example, a model is developed for an active-clamped SEPIC.

Active-clamp ZVS two-switch flyback converter

2011 IEEE International Symposium of Circuits and Systems (ISCAS), 2011
This paper introduces a zero voltage switching (ZVS) two-switch flyback pulse-width modulated (PWM) DC-DC converter along with the principle of circuit operation and steady-state analysis. The proposed converter topology is the result of incorporating an auxiliary circuit in place of the clamping diodes on the primary side of the conventional hard ...
