Seamless all-optical bidirectional wavelength converter

2016 15th International Conference on Optical Communications and Networks (ICOCN), 2016
We proposed a seamless all-optical wavelength converter based on four wave mixing effect in highly nonlinear fibers. The proposed wavelength converter consists of a section of highly nonlinear fiber to implement bi-directionally wavelength conversion twice for seamless conversion.

Hybrid bidirectional AC/AC multilevel converter

2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016
A new bidirectional multilevel converter topology called Hybrid Multilevel Converter (HMC) suitable for high power AC/AC applications is presented. It is based on cascaded connection of multiple half-bridge submodules in addition to nine thyristor-based low-frequency and soft-switched unfolders in a three-phase version.

Bidirectional control of inverse KY converter

2009 IEEE International Symposium on Industrial Electronics, 2009
An inverse KY converter, derived from the KY converter, is proposed herein. And such a converter can be used as a bidirectional converter, whose operating modes are classified into two modes. One is the buck mode and the other is the boost mode. This converter can operate stably between these two modes.

A bidirectional isolated DC-DC converter

2020 IEEE 9th Joint International Information Technology and Artificial Intelligence Conference (ITAIC), 2020
Aiming at the high switching voltage spikes and hard switching phenomena of traditional bidirectional isolated DC-DC converters, a bidirectional isolated DC-DC converter that can achieve zero voltage switching (ZVS) in the full power range is proposed. The two half bridges on the primary side of the converter are both Boost circuits, and the capacitor ...

Isolated bidirectional switched-capacitor flyback converter

2014 International Power Electronics and Application Conference and Exposition, 2014
In this paper, high-efficiency, extremely high step-up and step-down bi-directional DC-DC converter is proposed. The proposed converter consists of a flyback and an isolated switched-capacitor cell to achieve high cost competitiveness for the extreme operation. The output of the flyback converter and that of the isolated switched-capacitor is connected

The Bidirectional Multiresonant Converter

2003
The new bidirectional multiresonant converter is presented. The new converter is derived from the DE-class converter. The converter rectifiers are replaced by controlled bidirectional switch and bidirectional power flow is achieved in the same circuit. The converter performs different modes of operation.
