Abstract
There is provided a method for operating a control module of a high voltage switch, the method comprising: interfacing with an external environment via an input/output unit that filters each electrical signal passing therethrough; analyzing incoming signals and triggering actions as a function of the incoming signals via a logical unit; powering the control module via an internal power unit that is supplied by an external power supply; and isolating the logical unit from the power unit and the input/output unit by having all signals coming from these units and directed to the logical unit pass through an isolation unit.
