The Dynamic Characteriser for SiC Power Modules is a semi-automatic system for use in research laboratory to measure the switching characteristics of Silicon and Silicon Carbide Power Modules. The system provides clean measurement results under well-defined conditions, which can easily be correlated to simulation results of the device design and of the converter design. Switching characteristics are used to predict the actual behaviour of the SiC device in a converter. Important converter design parameters, like maximum allowed leakage inductance and parasitic capacitance and gate driver design parameters, are derived from the dynamic characteristics. The dynamic behaviour of the SiC power module is characterized by the voltage across and current through the DUT during turn-on and turn-off switching under defined circuit conditions. Characteristics like di/dt, du/dt, Eon, Eoff, Err, Irr, Vth, etc. as a function of the DC-link voltage, the output current, the junction temperature and gate driver settings quantify the dynamic behaviour and is input for calculations to optimize converter design. With this system the dynamic behaviour of the SiC power module can be measured at a DC-link voltage up to 2.5 kV, a current up to 500 A and a temperature up to 200°C. The modular system approach with exchangeable fixtures makes the system future proof for new module configurations and package styles.
