SYSTÈME ET PROCÉDÉ DE DÉTECTION D'HUMIDITÉ DESTINÉS À ÊTRE UTILISÉS DANS UN TRANSISTOR IGBT OU DANS UN TRANSISTOR MOSFET

摘要

A moisture detecting system has a power semiconductor module having a gate driver with the gate in which the gate driver has an on condition and an off condition, a power supply connected to the gate driver so as to supply voltage to the gate driver, a controller cooperative between the power supply and the gate driver so as to set the gate driver between the on condition and the off condition, and a sensor connected to the gate driver so as to detect a leakage of current across the gate driver. The controller is cooperative at the power supply so as to turn off the power supply when the signal is indicative of the leakage of current. The gate driver can an IGBT or a MOSFET.
