Isolation prevents high-voltage transients from motor windings or power switches from damaging low-voltage microcontroller circuits, eliminates ground loops that cause noise, and provides safety protection against electric shock.
Three primary types: optocoupler-based (light transmission), transformer-based (magnetic coupling), and capacitive-based (electric field coupling). Each has different speed, power, and cost characteristics.
Dielectric withstand testing (HIPOT) verifies insulation strength, partial discharge testing detects insulation defects, and common mode transient immunity testing measures noise rejection capability.
