What technologies exist for galvanic isolation? Galvanic isolation is a method of electrically separating two domains, allowing power or signals to transfer across the barrier without compromising human safety, while also preventing ground potential differences and improving noise immunity. Our portfolio of proprietary isolation techniques, including a robust capacitive SiO2 insulation barrier and integrated IC transformer-based magnetic isolation, helps exceed Verband der Elektrotechnik (VDE), Canadian Standards Association (CSA) and Underwriters Laboratory (UL) standards without compromising performance.
Addressing High-Voltage Design Challenges with Reliable and Affordable Isolation
High-voltage designs come with their own unique challenges. See how TI's magnetic and capacitive isolation technologies deliver greater lifetimes at a lower system cost for isolated systems in EV, grid infrastructure, factory automation and motor drive applications.
