Driver IC current rating and the driving capability is evaluated considering both switching loss and driver IC temperature rise. Short circuit protection performance is also evaluated in detail considering the faster switching speed and shorter withstand time of SiC MOSFETs. Experimental testing results ...

本期摘要 Power MOSFETs, IGBTs and wide bandgap (WBG) power devices are widely used in power electronic systems. As the Si-based power device technology is reaching its theoretical performance limit, more and more efforts have been placed on the gate driver design to further improve the device ...
A power supply with sufficient isolation is used to supply a standard driver circuit, whose input is optically or magnetically isolated from the rest of the control circuit, This technique has the advantage of providing the best rise times, and can operate at arbitrary duty cycles. It is ...
In case of a separate driver circuit, whether a gate drive IC or discrete solution, this capacitor must be placed close, preferably directly across the bias and ground connection of the driver. 2-11 There are two current components to consider. One is the quiescent current which can change ...
