IV Characterization of Power Semiconductors
Testing plays an important role at every stage of the development of SiC and GaN semiconductor devices, to characterize, benchmark, and document efficiency and other characteristics. It begins with testing the material to determine whether it is suitable for use. Once the device is fabricated, such as a MOSFET, breakdown voltage, leakage current, and OFF-state resistance testing must be done before it is installed on a circuit board.

Creating Battery Discharge Models and Simulating Batteries
A graphical SMU instrument can discharge a battery and create a model of the battery for use with a battery simulator. The model consists of both open circuit voltage and internal resistance as a function of the battery’s state of charge. The battery simulator will then emulate the battery using the created battery model and can be used under various testing conditions to see how the product performs when powered by a battery under various conditions of discharge.
