Method for applying coordinated power to operate multi-stage flash current and surge absorber devices uses triggers and purposeful commutating between single stages.

摘要

First (USG1) and second (USG2) surge absorbers in two classes (B,C) are decoupled. Together with a decoupling inductive resistor (UL), the second surge absorber forms a cumulative voltage (Up1=Up2+UL) to act as an ignition voltage for the first surge absorber. An Independent claim is also included for a device for applying coordinated power to operate multi-stage flash current and surge absorber devices.
