A Current-Fed Isolated Bidirectional DC–DC Converter

IEEE Transactions on Power Electronics, 2017
This paper proposes a current-fed isolated bidirectional DC-DC converter (CF-IBDC) which has the advantages of wide input voltage range, low input current ripple, low conduction losses, and soft switching over the full operating range. Compared with conventional CF-IBDCs, the voltage spikes of the low-voltage (LV) side switches in the proposed ...

Bidirectional high conversion ratio DC-DC converter

2012 IEEE Power and Energy Conference at Illinois, 2012
Recent trends in power conversion indicate a need for dc-dc power conversion at very high power levels and with high voltage buck/boost ratio for transmission/distribution purposes. No single conventional topology is well suited to these constraints.

Bidirectional isolated Γ-source DC-DC converter

2017 Iranian Conference on Electrical Engineering (ICEE), 2017
This paper presents a novel impedance-source bidirectional dc-dc converter. The proposed converter has a wide regulation range of voltage when comparing to conventional bidirectional dc-dc converters. Moreover, it has higher reliability due to elimination of the dead time and use of the shoot through states. The main advantage of this novel topology is

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 ...

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.

Low-loss bidirectional buck-boost DC-DC converter

Achievements of Modern Radioelectronics, 2021
For DC energy systems there is reversible buck/boost pulse converter (RPC) in the classic converter circuit. The maximum efficiency of the RPC without additional mechanisms to reduce the dynamic energy losses in the power semiconductor keys (PSK) during their commutation is about 92%. Improved efficiency is achieved by providing «soft switching» of the

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
