This paper provides an overview of galvanic isolation, explains common isolation methods for high-voltage systems, and shows how Texas Instruments (TI) isolation integrated circuits (ICs) can help designers meet isolation needs reliably while reducing solution size and cost.

1 What is galvanic isolation?	Galvanic isolation introduces electrical partitions that prevent current from flowing between two or more parts of a system. Isolating signals and power protects personnel and equipment and adheres to industry and international standards.
2 High-voltage galvanic isolation concerns	and methods Learn the primary considerations when constructing an isolation barrier, such as voltage ratings, spacing dimensions, common-mode transient immunity (CMTI) and electromagnetic interference (EMI).
3 Achieve isolation needs reliably while reducing solution size and cost	Advancements in capacitive and magnetic isolation, package development, and process technology from TI can deliver power and high-speed signals safely and reliably across the isolation barrier in industrial and automotive systems such as electric vehicles (EVs), grid infrastructure, factory automation and motor drives.
