Analog Devices demonstrates gate-driver board for Microsemi SiC modules at APEC

March 6, 2018

Norwood, MA (BUSINESS WIRE). Analog Devices Inc. in collaboration with Microsemi Corp. has introduced a high-power evaluation board for half-bridge SiC power modules delivering up to 1,200 V and 50 A at a 200-kHz switching frequency. The isolated board is engineered to improve design reliability while also reducing the need to create additional prototypes—saving time, lowering costs, and decreasing time to market for power-conversion and energy-storage customers. Analog Devices and Microsemi are showcasing the board at APEC 2018 through March 8 in San Antonio.

The new board can be used as the building block for more complex topologies, such as full-bridge or multilevel converters, for complete bench debugging of customer solutions. It can also function as a final evaluation platform or in converter-like configuration for full test and evaluation of Analog Devices’ ADuM4135 isolated gate driver with iCoupler digital isolation technology and LT3999 DC/DC driver in a high-power system.

The high-power evaluation board enables Microsemi’s SiC power modules to provide benefits such as a common test bench, higher power density for reduced size and cost, and isolated and conductive substrate and minimum parasitic capacitance for improved efficiency, performance, and thermal management. These attributes make the board suitable for applications including electric vehicle (EV) charging, hybrid EV (HEV)/EV onboard charging, DC/DC converters, switched-mode power supplies, high-power motor control and aviation actuation systems, plasma/semi cap equipment, lasers and welding, and MRIs and X-rays.
