The MPQ18913 can generate a +15/-4V or +15/-8V isolated power supply for biasing SiC or IGBTs, respectively. Other output voltage (VOUT) options can be achieved based on the design of the transformer and turns ratio.

These two failure modes are usually caused by temperature fluctuations [ 42, 43 ]. A. Solder-layer fatigue. There are two parts of the chip solder layer and DBC solder layer in the wire-bond IGBT module. Due to the diversity of packaging materials, the thermal expansion coefficients between the layers are different.

There is no need to have a complex gate driver since the IGBT has to be turned on way before firing the flash. Looking at the diagram, 15V should be sufficient as well. If the gate voltage is only let''s say 7V it won''t turn on completely. Unlike a Mosfet, IGBTs should be turned off using a negative voltage.
