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.

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 ...

Conference Proceedings., Eleventh International Telecommunications Energy Conference, 2003
It is demonstrated that it is possible to manufacture a very compact high-power switch-mode power supply based on the flyback technique using standard components, with no sacrifice in performance and operation at 80 kHz. A superior flyback converter can be designed on the basis of the following criteria: (1) choosing a pulse ratio to optimize the ...
