SiC Gate Driver Boards

Why

Wide bandgap semiconductors, in particular Silicon Carbide (SiC), are  offering a higher efficiency and an increased power density, making them a technology of choice for electrical vehicles (EV) and industrial power converters including motor drive inverters and battery chargers.

In order to take full advantage of the fast switching and low losses of SiC MOSFETs, two main challenges remain: having access to well optimized power modules featuring low parasitic inductances and finding a robust and fast gate driver to reliably and efficiently drive them.

What

CISSOID offers High Voltage Gate Driver boards rated at 125°C (Ta) optimized for 62mm and XM3 SiC MOSFET Power Modules:

• CMT-TIT8243 for 62mm/1200V SiC Power modules.

• CMT-TIT8244 for 62mm/1700V SiC Power modules.

• CMT-TIT0697 for XM3/1200V SiC Power modules.

They offer robustness against high dI/dt and high dV/dt as well as protections of the power module:

• Under voltage lockout (UVLO)

• Anti-overlap protection (on PWM inputs)

• Glitch suppressor (on PWM inputs)

• Active Miller Clamping

• Desaturation protection

• Gate-Source short-circuit protection

These gate driver boards provide thermal headroom for high density power converter design in automotive and industrial applications enabling high frequency (>100kHz) and fast switching (dV/dt>50kV/µs), improving efficiency and reducing size and weight.

CISSOID also offers custom gate driver boards for 3-Phase SiC MOSFET power modules leveraging on our Gate Driver technology at the heart of our 3-Phase SiC MOSFET Intelligent Power Modules.
