Abstract
Provided is a monitoring device for monitoring a control signal received by a power converter, the control signal controlling switches to supply an electrical load. The monitoring device includes a receiving circuit that receives the control signal comprising a merging of a first variable signal and a clock signal having a predetermined frequency greater than the first variable signal, a determining circuit that determines if a change of state of the control signal occurs during each period associated to the predetermined frequency, and a monitoring circuit that stops the transmission of the control signal to the power converter so that the power converter stops to supply the electrical load according to the instructions of the first variable signal if a change of state of the control signal does not occur during one period.
