A Three-Channel Package-Scale Galvanic Isolation Interface for Wide Bandgap Gate Drivers [PDF]

IEEE Transactions on Very Large Scale Integration (VLSI) Systems
This article presents the design of a three-channel package-scale galvanic isolation interface for SiC and GaN power switching converters. The isolation interface consists of two side-by-side co-packaged chips fabricated in a low-cost 0.32-μm bipolar ...

Modeling and Characterization of cMUT-based Devices Applied to Galvanic Isolation [PDF]

Physics Procedia, 2015
This paper describes a new way of using cMUT technology: galvanic isolation for power electronics. These devices work like acoustic transformers, except that piezoelectricity is replaced by cMUT technology.

Galvanically isolated SpaceWire

2014 International SpaceWire Conference (SpaceWire), 2014
The physical signaling layer for SpaceWire is specified in ECSS-E-ST-50-12C as LVDS per ANSI/TIA/EIA-644. LVDS is a current mode, differential interface that offers several benefits over other types of physical interfaces particularly in the areas of noise rejection, electromagnetic noise generation, and power supply decoupling.

Semiconductor-based galvanic isolation

2015 IEEE 3rd Workshop on Wide Bandgap Power Devices and Applications (WiPDA), 2015
This paper presents the study on the semiconductor-based galvanic isolation. This solution delivers the differential-mode (DM) power via semiconductor power switches during their on states, while sustaining the common-mode (CM) voltage and blocking the CM leakage current with those switches during their off states.

Session 25 overview: GaN drivers and galvanic isolators

2017 IEEE International Solid-State Circuits Conference (ISSCC), 2017
Gallium-Nitride (GaN) power devices have garnered a lot of attention for their reduced switching losses leading to small-form-factor high-frequency switching converters. However, issues related to reliable GaN gate driving, signal and power isolation with high common-mode immunity, and reduced electromagnetic interference (EMI) need special attention ...

Giant magnetoresistive based galvanically isolated voltage measurement

2014 IEEE International Workshop on Applied Measurements for Power Systems Proceedings (AMPS), 2014
Nowadays direct current (DC) is much more widely used than a decade ago. Not only in the well-known high voltage direct current (HVDC) transmission but also as DC powered marine system, DC data center and DC fast charging system for electric vehicles. DC is now challenging the alternative current (AC) in a large variety of fast growing markets. However

A Capacitive Galvanically Isolated Full-Bridge Converter

IEEE Transactions on Transportation Electrification
This paper proposes a transformerless, capacitively isolated converter based on a full-bridge topology with phase shift control. Compared to existing capacitively isolated converters, the proposed design offers the advantage of zero mean voltage across the isolating capacitors, thereby reducing voltage stress.
