Analog Devices iCoupler isolated gate drivers are combined with Wolfspeed’s market leading MOSFETS to deliver high efficiency and high reliability system solutions across industrial, energy and automotive applications.

This video reveals the nuances and details of a successful SiC design. Gate driver considerations are examined including understanding datasheet test conditions for driving switches, and reducing switching loss including hidden resistive elements like RDSON and the switches internal gate resistance. Saturation considerations are reviewed for both SiC MOSFETS and IGBTs. The necessary SCP (short circuit protection) is discussed including typical fault detection methods. The positive impact of higher Common-Mode Transient Immunity (CMTI) to increase efficiency, the minimization of circuit parasitics and optimized DESAT detection and soft shutdown are also investigated.
