This paper analyzes how a previously presentedadaptive open loop gate driver handles fault currents. Whencontrolling insulated gate bipolar transistors (IGBTs), it isessential to ensure safe operation in the whole operating range.Most important, the gate driver must be able to safely turn OFFa unacceptably high current like a short-circuit current. Such afault generates a current of unknown magnitude, which has tobe switched off as safe and slow as possible. A special shutdownmode of the investigated open loop gate driver is presented in thispaper, which makes it possible to safely shut down a fault currentwithout knowing the actual operating point of the IGBT. Basedon measurement results it is shown that all currents, includingdesaturation of the IGBT can be safely turned OFF.

2019 21th European Conference on Power Electronics and Applications (EPE'19 ECCE Europe)

This paper presents a new gate driver concept that allows an online, open-loop adjustment of the switching behavior of power semiconductors during operation. An inductive impedance instead of an ohmic impedance enables the required adjustable gate current and thus the desired gate voltage curve. The driver can individually adapt the switching behavior of the transistor to each individual switching edge. Thus for example the dv/dt and di/dt can be influenced, whereby the EMI behavior, the reverse recovery rate, the occurring overvoltage or the switching losses can also be influenced. The new gate driver was compared to a conventional resistive gate driver and the measurement results clearly show the advantages of the proposed driver concept.

"This paper presents a multi-dimensional full automatic semiconductor test bench for accurate semiconductor
loss determination. The test bench is based on the double pulse test and allows the measurement
of conduction losses and switching energies for any current, voltage and temperature combination of the
device under test. A conduction- and switching loss analysis is presented for silicon carbide (SiC)- and
silicon (Si)-based semiconductor devices. Distinct differences of datasheet information and measurement
results demonstrate the significant benefits of the designed test bench for an accurate semiconductor loss
calculation. Afterwards the semiconductor loss calculation results based on the data sheet data and the
measured losses are compared."
