Critical Components Behind Switch-mode Power …

Varistors are voltage-dependent resistors whose resistance decreases with increasing voltage. Connected in parallel with the electronic device, or circuit that is to be protected, a varistor forms a low-resistance shunt when voltage increases. Common overvoltage sources include lightning, inductive load switching and electrostatic discharge (ESD).
