CISSOID and DDC cooperate on more compact and reliable SiC intelligent power modules

Fabless high-temperature and and extended-lifetime semiconductor firm CISSOID of Mont-Saint-Guibert, Belgium is collaboratingwith Data Device Corp (DDC), which designs and manufactures data bus, motion control and solid-state power controller products for aerospace, defense and industrial applications, and with DDC subsidiary Beta Transformer Technology Corp (BTTC), which produces military, commercial and space-level magnetic components, for the development of more compact and reliable silicon carbide (SiC) MOSFET intelligent power modules (IPM) for aerospace power converters and motor control.

BTTC will develop high-reliability and high-temperature transformer modules, embedding both power and pulse transformers, optimized for CISSOID's HADES2 isolated gate driver. This solution will be used in the SiC MOSFET intelligent power modules developed by CISSOID, making them more compact and reliable. It will address SiC IPMs developed for high-power-density applications as well as IPMs in hermetically sealed packages currently in development for harsh environments (e.g. unpressurized locations and/or extreme temperatures).

The first transformers modules are being developed, validated and qualified for temperature ranges from -55°C up to +225°C. Magnetic cores and other transformer materials have been selected to offer stable behaviour and reliable operation within this range. The transformers will provide isolation in excess of 2500Vdc and are optimized for very low parasitic capacitances in order to support high dV/dt, typically up to 50KV/µs (common with fast-switching SiC transistors). These transformers have been optimized to work with the HADES2 isolated gate driver chipset: the power transformer is used inside a flyback DC-DC converter supplying both low- and high-side isolated gate drivers while pulse transformers are transmitting PWM and Faults signals.

"With DDC and BTTC, we found the right partners to develop high-reliability and high-temperature transformer solutions for our SiC IPM and gate drivers. They bring to CISSOID their long experience in developing signal and power transformers for data transceivers and power converters as well as their high quality manufacturing facilities." says CISSOID's CEO Dave Hutton. "This partnership shows CISSOID's commitment to work with partners to offer to its customers a complete ecosystem for the development of high-temperature system solutions," he adds.

"This first partnership with CISSOID will trigger others as we see various collaboration opportunities between DDC and CISSOID, e.g. the developement high-temperature motor drive or power converter solutions for aerospace, defense and industrial applications," believes Frank Bloomfield, VP Power Systems at DDC.
