The topologies research of a soft switching bidirectional DC/DC converter

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
A soft-switching solution implemented to the traditional bidirectional DC/DC converter is developed. The soft-switching cell, which composed of three auxiliary switches, one resonant capacitor and one resonant inductor, is equipped in the traditional bidirectional DC/DC converter to realize circuit ZCT or ZVT operations in both energy transmission ...

A novel bidirectional PWM dc-dc converter

2008 Canadian Conference on Electrical and Computer Engineering, 2008
A new soft-switched bidirectional dc-dc converter is proposed in the paper. The proposed converter can operate with soft-switching, a continuous inductor current, fixed switching frequency, and the switch stresses of a conventional PWM converter regardless of the direction of power flow. These features are due to a very simple auxiliary circuit that is

A new bidirectional zeta DC/DC converter

The 5th Annual International Power Electronics, Drive Systems and Technologies Conference (PEDSTC 2014), 2014
Nowadays, applications of DC-AC inverters in various applications such as hybrid electric vehicles are growing up. DC-DC converters are one of the important parts of the HEVs. Dual output DC-AC inverters can be used in them. If a multi input-multi output inverter be used, then the DC-DC converter should be able to prepare the inputs for that.

A ZCS Bidirectional Flyback DC/DC Converter

IEEE Transactions on Power Electronics, 2004
This paper addresses the design and analysis of a zero-current-switched (ZCS) bidirectional 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 ...

Control loop design and bidirectional control strategy of a bidirectional DC/DC converter

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
In this paper, one kind of two-stage bidirectional AC/DC converter for battery formation is studied. And the post-stage DC/DC converter based on the full-bridge and push-pull structure is the focus of the study. Firstly, the small signal model is built for the bidirectional DC/DC converter. And then the control compensator is designed.
