High Power And High Voltage Isolated Gate Driver Board By Analog Devices Promises Lesser Time Consumption

Analog Devices Inc. recently introduced a high power evaluation board for half-bridge SiC power modules that have a switching frequency up to 50 A @ 200 KHz and 1200 V. The firm teamed up with Microsemi Corporation for this purpose. The isolated board has been engineered to improve design reliability while eliminating the need of prototype creation to quite an extent. This would invariably save time, reduce costs, and bring down the time needed to bring a product into market. The two firms showcased this product at the 2018 APEC that took place in San Antonio, Texas.

This new board will be used as a building block for more complicated topologies like multilevel converters or full-bridge converters. It will also work as a final evaluation platform in configurations closely relating to converters as well as in analysis of ADuM4135, an isolated gate created with iCoupler digital isolation technology as well as LT3999 DC-DC driver in high power systems. The later two are from the house of Analog Devices.

This high power evaluation board would also allow Microsemi’s SiC power modules that will offer benefits like common test bench and better density of power for lesser size and cost, minimum parasitic capacitance and conductive substrate for better efficiency, as well as at par thermal management. These characteristics make this board perfect for several applications like DC-DC converters, EV (Electric Vehicle) charging, high-power motor control, aviation actuation systems, welding, X-Rays, MRIs, and so forth.
