Microchip introduces integrated actuation power solution for electric aircraft

April 23, 2024
Microchip introduces configurable family of companion driver boards using its Hybrid Power Drive modules available in silicon carbide (SiC) or silicon (Si) technology.

CHANDLER, Ariz., - Microchip Technology in Chandler, Ariz. has introduced a new integrated actuation power solution to meet  the aviation industry's push for sustainability and decarbonization and the adoption of electric actuation systems in aircraft.

The solution combines companion gate driver boards with Microchip's Hybrid Power Drive (HPD) modules, available in silicon carbide or silicon technology with a power range of 5 kVA to 20 kVA.

The integrated system maintains a consistent footprint regardless of power output and is designed to be used in various applications including flight controls, braking, and landing gear electrification.

The devices undergo rigorous testing to meet aviation standards outlined in DO-160, ensuring high reliability. They feature multiple protection features such as short circuit protection and under-voltage lockout.

Designed for low electromagnetic interference and noise immunity, the gate driver boards utilize external PWM signals compliant with TIA/EIA-644 standards. They provide telemetry outputs for monitoring critical parameters such as current and temperature.

Compact and lightweight, the gate driver boards are designed to operate in harsh environments, withstanding temperatures ranging from −55°C to +110°C. Additionally, they require only a single 15V DC input, simplifying system design and cabling.

"We developed the companion gate driver boards to be used with our existing HPD modules to bring to market a plug-and-play power solution for MEA," said Leon Gross, vice president of Microchip’s discrete product group. "With this solution, customers no longer need to design and develop their own drive circuitry, which can reduce design time, resources, and cost."
