EMI analysis of a DC-DC converter using a piezoelectric transformer
2009 35th Annual Conference of IEEE Industrial Electronics, 2009Power electronic converters based on piezoelectric transformer (PT) have been widely adopted in recent years due to their many inherent advantages such as safety, low housing profile and high power density. However, few studies have been conducted about noises emitted by PT converters [1].

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

A Resonant DC-DC transformer with Zero Current Ripple
IEEE 36th Conference on Power Electronics Specialists, 2005., 2006The paper presents a resonant converter topology capable of providing zero ripple conditions (ZRC) at either its input or output current. The basic properties of the proposed topology are discussed in detail. The remarkable symmetry and the proportional voltages of the circuit allow it to maintain ripple-less current independent of the load or ...

Developing DC Transmission Networks Using DC Transformers
IEEE Transactions on Power Delivery, 2010This paper studies principles of developing dc transmission grids based on high power dc/dc converters. There has been much research on dc/dc converters and it is likely that some megawatt size units will achieve commercialisation stage soon. In this study, we assume that electronic dc transformers can achieve three functions: 1) voltage stepping, 2 ...

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 ...
