Power converters are the key point for the new electrical grids. They allow an optimal energy management and can participate in the protection strategies. Regarding the voltage and power levels of these converters, the efficiency has to be high (above 99 %). On the other hand, the trend in to increase the switching frequency of these converters in order to reduce the size of the passive components. In power converters, the main contributors in the power losses are the power electronics switches which generate both conduction and switching losses.

Consequently, during the topologies studies and the design of the converters, accurate models are required to predict the efficiency. These models should be valid for several operating points (voltage, current, temperature levels) and for several switching modes (hard or soft switching).

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

• Power switches characterization
• Power semiconductors characterization
• Simulation models generation
• Robustness & reliability tests

• The static and dynamic characterization 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 characterization 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
