Description

To generate these models, SuperGrid Institute is capable to perform the following characterisations:

Static & Dynamic characterisation

  • Static characterisation (i-v): up to 5 kV-1,5 kA

  • Capacitance measurement: up to 3 kV

  • Leakage current measurement: up to 30 kV

  • Double pulse test bench: up to 20 kV-100 A

  • Dynamic characterisation in hard & soft switching: up to 10 kV-3 kA

  • Thermal impedance measurement

  • Datasheet generation

SuperGrid Institute offers a complete solution to characterize the power electronics devices and generate accurate datasheet or simulation models:

All the tests can be performed for different temperatures.

Power converters are the key point for the new electrical grids. They allow an optimal energy management and can participate in the protection strategies.

Specific tests can be achieved according to the customer’s needs.

Robustness & reliability tests

To determinate the correct operating conditions of the switches that ensure the required lifetime for power electronics systems:

  • High Temperature Gate Bias (HTGB)

  • High Temperature Gate Switching (HTGS)

  • High Temperature Reverse Bias (HTRB)

  • Repetitive avalanche tests

  • Repetitive short circuit tests

Added value

  • The static and dynamic characterisation are coupled with multi-physic simulation tools, so that accurate models of switches can be generated. These models allows optimized design of power electronics systems.

  • The dynamic characterisation can be achieved in spontaneous and controlled switching. Consequently, the switching losses can be estimated in hard and soft switching modes.
  • Specific tests can be achieved according to the customer’s needs.
