MOSFETs and Transformer VCC_U_B VEE_U_B Turning an IGBT on and off amounts to charging and discharging large capacitive loads, so the peak charge current needs to be within the capability of the drive circuit. At the same time, the driver will have to draw this peak charge current from...
The Infineon gate driver 1ED020I12-B2 provides a short circuit detection by measuring the VCEsat voltage of the IGBT. If a short circuit occurs, the collector current and the saturation voltage increase. If the IGBT is commanded on stated and the VCE reaches 9V a short circuit is detected...
In case of a defect in one of the LLC MOSFETs, the gate might become a short-circuit to the drain, and the bulk voltage consequently would be applied to the gate driver IC. Since the driver IC is placed across the reinforced isolation barrier, it is of system safety rele...
