Low cost galvanic isolation amplifier
International Journal of Electronics, 1986A simple circuit is described in which a dual opto-isolator integrated circuit is used as the basis of a circuit to give galvanic isolation for analogue signals. The isolation voltage obtained is ± 1500 V. The circuit which is designed using low cost components gives a linearity of better than 1%.

A Capacitive Galvanically Isolated Full-Bridge Converter
IEEE Transactions on Transportation ElectrificationThis 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.

Highly Integrated Galvanically Isolated Systems for Data/Power Transfer
2019 26th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2019This focus paper gives a panorama of galvanically isolated power/data transfer systems. It starts from a review of state-of-the-art isolation technologies and describes most advanced system architectures. Among these, approaches capable of reducing the number of isolated links, while preserving power and data functionalities will be presented.

Accurate voltage-to-frequency sensor with galvanic isolation and bandwidth of 375kHz
2020 IEEE Industry Applications Society Annual Meeting, 2020High-bandwidth low-cost MV voltage sensors with appropriate isolation are required in MV power electronic converters for utility and industrial applications. It is especially critical in low-inertia converters (reduced passives) due to the existence of fast dynamics with reduced storage elements (dc-link, filters etc.).

Galvanically isolated driver using an integrated power- and signal-transformer
2015 IEEE International Conference on Industrial Technology (ICIT), 2015Galvanically isolated drivers offer a good protection of the control part against EMI caused by the switching transients of the high power electronic devices. The proposed concepts aims to reduce the component count and building height by using one integrated magnetic core for the power and signal transformer.

Giant-Magnetoresistance-Based Galvanically Isolated Voltage and Current Measurements
IEEE Transactions on Instrumentation and Measurement, 2015Nowadays, dc current is much more widely used than a decade ago, not only in the well-known high-voltage dc transmission but also as dc-powered marine systems, dc data centers, and dc fast charging systems for electric vehicles. However, galvanically isolated dc voltage or current sensors are, in terms of accuracy, noise level, or dimensions, still far

Performance Evaluation of CMUT-Based Ultrasonic Transformers for Galvanic Isolation
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2018This paper presents the development of a novel acoustic transformer with high galvanic isolation dedicated to power switch triggering. The transformer is based on two capacitive micromachined ultrasonic transducers layered on each side of a silicon substrate; one is the primary circuit, and the other is the secondary circuit.

Bidirectional softly switched dc-to-dc converter with galvanic isolation
2015 IEEE International Conference on Industrial Technology (ICIT), 2015Bidirectional power flow in energy storage facilities is common and required. Energy supply from energy storages and energy imbursement back to the storages and preferably at high-efficiency are basic operations for these kinds of equipment. Since the boom growth on uninterruptable power supplies for critical loads and electric vehicles, storages ...

cMUT technology applied to galvanic isolation: Theory and experiments
2015 IEEE International Ultrasonics Symposium (IUS), 2015This study relies on double-sided chips where capacitive Micromachined Ultrasonic Transducers (cMUT) are manufactured on both sides of a silicon substrate in order to perform galvanic isolation between two electrical circuits. The operating principle is based on the propagation of acoustic waves from one transducer to the other, providing a high level ...
