“…In [11], a fault current detection using a printed circuit board Rogowski coil is used in a gate driver to protect 4.5 kV press-pack IGBTs operated at 4 kA of pulse current. Detection circuits using the turn-on switching characteristic to protect IGBTs under short-circuit failures are represented in [12]- [15]. These scheme are based on the gate voltage behavior at the turn-on transient of IGBTs, and to obtain an early detection failure.…”

This paper presents the development of a short-circuit protection mechanism on a high voltage switch (HVS) board which is built by a series connection of semiconductor switches. The HVS board is able to quickly detect and limit the peak fault current before the signal board triggers off a gate signal. Voltage clamping techniques are used to safely turn off the short-circuit current and to prevent overvoltage of the series-connected switches. The selection method of the main devices and the development of the HVS board are described in detail. Experimental results have demonstrated that the HVS board is capable of withstanding a short-circuit current at a rated voltage of 10kV without a di/dt slowing down inductor. The corresponding short-circuit current is restricted to 125 A within 100 ns and can safely turn off within 120 ns.

This paper presents a novel piezoelectric sensor, which is integrated in power modules and analyzes temperature and thermal-mechanical stress in real time. Due to the increased power density, recent power modules are often exposed to high operating temperatures. Thus, it is critical to measure temperature and (related) thermal stress in power modules. The piezoelectric sensor proposed herein is fabricated by attaching PZT pieces on a direct bonded copper (DBC) substrate. Heat from operating power devices deflects power substrates and generates thermal stress, which is picked up by in-built piezoelectric sensors optimally located at critical locations. As the sensor locations are away from heatgenerating power devices, their effects on device performance are negligible. Both simulation and experiment results demonstrate that the proposed sensor provides a very good linearity (R 2 = ~0.99) in the temperature range from 40°C to 160°C. This sensor characteristics were consistent in different measurements. Therefore, our in-built piezoelectric thermal sensor facilities reliable in-situ monitoring of temperature distribution and thermal stress in power modules experiencing high temperatures.
