Transformer-less DIDO DC-DC converter for EV's
2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016A transformer-less dual input dual output (DIDO) dc converter is proposed in this paper. This converter finds its application in fields of hybrid power system and hybridization of energy sources for electric vehicles. Supply of the output loads, charging and discharging of the battery / energy storage system can be made from the fuel cells (FC) or ...

Computer-aided analysis of electronic DC-DC transformers
IEEE Transactions on Industrial Electronics, 1988An approach to the analysis of electronic DC-to-DC transformers using the SPICE simulation program as an aid is presented. In this approach, the minimum separable switching configuration (MISSCO) of a DC-to-DC transformer is first identified and its equivalent circuit determined before analysis and simulation are carried out on the complete converter ...

Dual-output DC-DC power supply without transformer
2004 IEEE Region 10 Conference TENCON 2004., 2004This paper proposes an application of the topology converter to dual-output DC-DC power supply, combining buck-boost with zeta converter. By the combination, only single control switch can be used to regulate dual output voltage and only single inductor at the input of the converter can be used provided the same converter ratio. In addition, the output

Virtual Transformer Control for DC-DC Interlinking Converters in DC Microgrids
2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019In a DC microgrid, a converter connecting two DC buses is a DC-DC interlinking converter (ILC). In the ILCs, this paper proposes a simple control solution to handle two control issues simultaneously: a) high-voltage-side-series low-voltage-side-parallel (HSLP) modular ILC, b) control adaptability in different grid-working modes.

2013 IEEE Power & Energy Society General Meeting, 2013
This paper presents a transformer-less dc-dc converter with large voltage gain for medium voltage dc grid applications. The converter is based on a combination of boost converter and a series-parallel resonant circuit with capacitive output filter. Soft-switching of the power switches and diodes are naturally achieved due to the resonant operation. The

High frequency transmission line transformer for DC/DC converters
Proceedings of PESC '95 - Power Electronics Specialist Conference, 2002A high frequency transmission line transformer for DC/DC power converters is proposed. A DC isolated transformer is formed using cascades of interconnected transmission line sections. The energy transfer takes place via electromagnetic waves. The distinct feature of the transformer is that the voltage ratio is determined solely by the characteristic ...

Design guidelines for DC/DC converter using piezoelectric transformer
IEEE 2002 28th Annual Conference of the Industrial Electronics Society. IECON 02, 2003Piezoelectric transformers (PTs) have lately been looked upon as an attractive solution to reduce size and weight in AC/DC converters. This paper presents a topology that includes such a device while minimizing the number of additional components required for an adequate performance.
