Method and measurement system for dc characteristics measurement of power diodes in very wide current range
2012
The new measurement set-up of DC characteristics of power diodes measurements was presented. Authors proposed to organize measurements in a pulse manner, because in typical method junction temperature of power diodes under test during measurements increase. The system elaborated on the base of method for measuring DC in a very wide current range which utilizes modified R-2R resistor ladder (short-circuit keys instead of switching keys) was constructed. The measurement system is controlled by the computer with LabView application that allows to apply measurement procedure in a very short time. Key-words: SiC power diode, measurement, DC characteristic.
