Why galvanic isolation? In EVs and HEVs, when the grounds of two distinct circuits are at different electrical potentials, galvanic isolation is necessary to prevent the triggering of dangerous ground loops, which can generate noise that could compromise the safety of the vehicle.

Why do we need galvanic isolation?

Galvanic isolation separates the input and output supplies to a device so that energy flows through a field rather than via electrical connections. It enables power transfer between two circuits that must not be connected.

What is galvanic isolation?

Galvanic isolation is a design technique that separates electrical circuits to eliminate stray currents. Signals can pass between galvanically isolated circuits, but stray currents, such as differences in ground potential or currents induced by AC power, are blocked.
