SiC intelligent power modules platform expanded for e-mobility

30-04-2021 | Cissoid | Power

CISSOID adds to its growing platform of three-phase SiC MOSFET Intelligent Power Module products by releasing new liquid-cooled modules for E-mobility tailored for lower switching losses or higher power. The company is also releasing a module based on a lightweight AlSiC flat baseplate that satisfies the demand for natural convection or forced cooling in aerospace and dedicated industrial applications. These products integrate a three-phase SiC MOSFET module with a powerful gate driver.


These new IPMs use a technology platform that may be rapidly modified to new voltage, power and cooling demands. They greatly expedite the design of SiC-based power converters facilitating high efficiency and high-power density. The embedded gate driver solves multiple challenges associated with fast-switching SiC transistors: negative drive and AMC prevent parasitic turn-on; Desaturation detection and Soft-Shut-Down react swiftly but safely to short-circuit events; UVLO functions on gate driver, and DC bus voltages monitor the proper operation of the system.


The new-air cooled module is intended for applications where liquid cooling is not an option, like aerospace electromechanical actuators and power converters. This module is rated for a blocking voltage of 1200V and a Maximum Continuous Current of 340A. The On resistance is equal to 3.25mOms. Turn-on and turn-off switching energies are respectively 8.42mJ and 7.05mJ at 600V and 300A. The power module is cooled down via an AlSiC flat baseplate. Thermally robust, the module is rated for 175C junction temperature and the gate driver for 125C ambient temperature.


"We initially developed this IPM platform to accelerates SiC-based motor drives development for E-Mobility, and we are also very pleased to see demand from aerospace customers," says Dave Hutton, CEO at CISSOID. "We are delighted to deliver this new SiC intelligent power module designed for natural convection or forced cooling in compact and lightweight power converters addressing these new demanding markets."
