What is Galvanic isolation
Galvanic isolation is a principle in electrical engineering that involves separating electrical circuits to prevent the flow of direct current (DC) and unwanted alternating current (AC) between them, while still allowing the transfer of signals and power. Essentially, there is no direct conductive path between the isolated circuits; instead, energy or information is transferred via a field (magnetic, electric, or light). Here's a breakdown of the concept and its function: Function: Prevents DC and Unwanted AC Current Flow: The primary function is to block any direct electrical connection between circuits. This is crucial when there are significant differences in ground potential or when high voltages are present in one part of the system that could be dangerous to other parts. Allows Signal and Power Transfer: Despite the electrical separation, galvanic isolation allows the necessary signals and power to be transmitted between the isolated circuits. Th...
