Patent number: 6836125Abstract: A method of testing a power module including a control gate, an emitter, a collector, at least one power component on a dielectric substrate and a diode connected in antiparallel with the power component measures partial discharges occurring between the emitter and the collector when an alternating current voltage source superimposed on a direct current voltage source is connected between the collector and the emitter of the power module. The voltage Vtest received by the power module between the collector and the emitter verifies at all times the condition Vtest>0 so that the diode never conducts. The power component is maintained in a turned off state during the test by a direct current voltage source connected between the control gate and the emitter.Type: GrantFiled: July 23, 2002Date of Patent: December 28, 2004Assignee: AlstomInventors: Fabrice Breit, Sorin Dinculescu, Emmanuel Dutarde, Thierry Lebey, José Saiz
