Insulated-gate bipolar transistors (IGBTs) operated in short circuit become instable in certain driving and load conditions. The induced oscillations can compromise robustness and reliability of the entire power converter. The stability of the device inserted in a real system can be analyzed using the theory of linear oscillators that requires the knowledge of input or output impedance of the device in real operating conditions. In this paper, we present an experimental procedure for measuring… CONTINUE READING
