Power Integrations announced the SCALE-iFlex™ gate-driver system for IGBT, hybrid and silicon-carbide (SiC) MOSFET power modules with blocking voltages from 1.7 kV to 4.5 kV. The system consists of a central Isolated Master Control (IMC) and one to four Module-Adapted Gate Drivers (MAGs). The IMC provides a 4.5 kV blocking voltage. A range of MAGs is available to service a variety of power modules, suppliers and semiconductor switch technologies across 1700 V, 3300 V and 4500 V voltage classes.
The SCALE-iFlex gate-driver system enables easy paralleling of the industry’s latest dual power modules, providing reliable and highly flexible system scalability with minimum development effort. The MAG is placed adjacent to the modules’ control terminals to provide excellent switching performance, and the IMC performs all necessary communication between the MAGs and the user’s MCU handling functions such as PWM commands, short-circuit and under-voltage failure reporting, as well as NTC and DC-Link voltage measurement (more info, graphic: Business Wire).
