SiC MOSFETs and gate driver board introduced at PCIM Europe

Among the exhibits at the Cissoid stand (Hall 7-552) will be high temperature gate drivers, SiC MOSFETs and power modules.

A gate driver board optimised for 62mm silicon carbide (SiC) MOSFET power modules rated at 125 degrees C will be introduced. It is based on Cissoid’s Hades gate driver chipset. It can also drive IGBT power modules wand offers thermal headroom for the design of high density power converters in automotive and industrial applications. The gate driver board enables high frequencies of above 100KHz and fast SiC MOSFET switching at dV/dt up to 50kV/micro seconds. The board is designed to improve efficiency and reducing size and weight of the power converters. It can be used in harsh voltage environments supporting 1200 and 1700V power modules with isolation voltages up to 3600V (50Hz, 1min) and creepage distances of 14mm.

Protection functions include under-voltage lockout (UVLO), active miller clamping (AMC) and desaturation detection.

Cissoid will also present new SiC MOSFETs and IGBT power modules. A discrete 1200V/40mOhms SiC MOSFET is available in a TO-247 package and operates from -55 to 175 degrees C. The MOSFET has a drain to source on resistance of 40mOhms at 25 degrees C (Tj) and 75mOhms at 175 degrees C (Tj). Low switching turn-on and turn-off energies of 1mJ and 0.4mJ respectively, make this SiC MOSFET suitable for efficient and compact DC/DC converters, power inverters and battery chargers.

The company will also present two 62mm 1200V IGBT power modules with 200 and 300A current rating.

Cissoid specialises in high temperature semiconductors for demanding markets. The company specialises in the automotive market for which it provides efficient power conversion and compact motor drives, high voltage gate drivers for SiC and GaN transistors, power modules and automotive -grade components rated at 175 degrees C in excess of the AEC-Q100 Grade 0 qualification standard.

For the aviation, industrial and oil and gas markets it provides harsh environment signal conditioning, motor control, timing and power supplies that provide reliable operation from -55 to +225 degrees C.
