The Asymmetrical Half-Bridge Flyback Converter: a Reexamination
2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020Isolated Zero-Voltage-Switching (ZVS) dc-dc converter topologies are attractive solutions in the continuous ride toward higher switching frequencies, allowing more compact power supplies. Among them, the Asymmetrical Half-Bridge Flyback Converter (AHBFC) represents an interesting solution, featuring a simple duty-cycle control at a constant switching ...

A Constant Current Digital Control Method for Primary-Side Regulation Active-Clamp Flyback Converter
European Conference on Cognitive Ergonomics, 2020Active-clamp flyback converter is now widely used because higher efficiency is obtained with soft-switching technique. However, opto-coupler is always applied in the feedback loop to acquire the output signal.

Sensorless BCM control for a bidirectional flyback-converter
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016Transducers based on dielectric elastomers (DE) represent capacitive loads from an electrical point of view. Thus, for an efficient operation of these transducers tailored power electronics are required, preferable with bidirectional energy flow to improve the energy efficiency.

A lossless current sensing technique for flyback converters
2009 35th Annual Conference of IEEE Industrial Electronics, 2009Regardless of the feedback control, almost all converters require input or output current sense for overcurrent protection. If a current mode control is implemented, high accuracy is also required. The optimal current sensing method shows the highest accuracy and the lowest power dissipation.

A Digital Control Scheme for PSR Flyback Converter in CCM and DCM
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020Due to the simple structure and low cost, the primary-side-regulation (PSR) flyback converter is widely used in small power applications. As the output voltage is sampled from auxiliary winding in PSR flyback converter, some sampling error exists ...

An overview of soft-switching technique for flyback converters
2015 IEEE 11th International Conference on ASIC (ASICON), 2015Flyback topologies are widely used in low power applications due to the small size and low cost. To improve the efficiency via reducing the switching loss, valley switching technique is introduced and several methods to realize valley switching are analysed and compared.

Design and implementation of an integrated boost-flyback converter
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015This paper presents design and implementation of a Integrated boost-flyback converter (IBFC). Operation of the IBFC is described and its key voltage and current equations are given. The practical design of a 96W, 12V-to-48V, IBFC is demonstrated. Experiment on the prototype IBFC shows that it operates with good output voltage regulation and achieves ...

A DC-DC converter with dual flyback converter topology
2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2013A new two-switch flyback converter is proposed in this paper. The most attractive feature of the proposed converter is that both of its main power switches can be made to operate with zero-voltage switching (ZVS) with the help of just one auxiliary circuit consisting of just one active auxiliary switch and a capacitor.
