Fuzzy based bidirectional converter

2015 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2015], 2015
The core topic of the paper discuses bidirectional buck/boost converter implemented using soft switching. In addition to a soft switched DC-DC conversion, the circuit also facilitates an additional output which makes the system capable of supporting multiple applications. The circuit under discussion uses fuzzy logic for the closed loop operation which

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,

A ZCS bidirectional flyback converter

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
This paper addresses the design and analysis of a zero-current-switched (ZCS) bi-directional flyback dc/dc converter. The converter is based on extending a previously developed unidirectional ZCS flyback converter and replacing the output diode with a controlled switch, which acts as either a rectifier or a power control switch in the corresponding ...

A bidirectional AC/AC multilevel converter

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
A new AC/AC multilevel converter topology suitable for high power applications is presented. The proposed topology has less number of IGBT switches and capacitors compared with traditional approaches. In addition, more than half of the switches are operating in soft switching condition, which considerably decreases the switching losses. The theoretical

A bidirectional dc-ac converter

IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012
This paper proposes a bidirectional grid interface converter to be applied in Energy-Control-Center (ECC) in order to interface dc variables, such as battery energy storage system and ac conventional utility grid. Such power electronics solution guarantees: (i) bidirectional power flow between dc and ac converter sides, (ii) independent control in both
