Dynamic gate stress tests help engineers qualify SiC and GaN devices.
The DGS test system converts the extended requirements from industry into automated dynamic tests, emphasizing flexibility to quickly adapt to changing requirements.
In addition to the stimuli, the DGS test system also offers numerous in-situ measurements to determine relevant parameters in a defined time period.
In-situ measurements show efficiently the long-term effects of dynamic gate stress on the gate oxide and enable you to provide precise statements to your customer.
Supports up to 240 DUTs with hot/cold plate temperatures ranging from 20 °C to 200 °C.
Offers high-voltage drain stimuli up to 1.5 kV and maximum drain voltage up to 1500 V, both software configurable.
Features high dV/dt stimuli of the gate up to 1 V/ns, with software-configurable voltages up to ±30 V max.
Provides configurable output frequencies from 0 Hz to 500 kHz, with duty cycle settings ranging from 25 percent to 75 percent in five percent steps.
Enables testing with application-specific gate drivers for targeted assessments.
Frank Heidemann, VP & Technology Leader, explains how to stress the gate with voltage changes to create trapping effects, causing Vth and RDS(on) drifts in wide-bandgap semiconductors, which is crucial to reveal efficiency losses in these components.
NI offers a variety of solution integration options customized to your application-specific requirements. You can use your own internal integration teams for full system control or leverage the expertise of NI and our worldwide NI Partner Network to obtain a turnkey solution.
NI works with customers throughout the life of an application, delivering training, technical support, consultation and integration services, and maintenance programs. Teams can discover new skills by participating in NI-specific and geographic user groups and build proficiency with online and in-person training.
