Simplified Aircraft Electrification with Actuation Power System
April 17, 2024
The aviation industry is constantly evolving to meet the demands of sustainability and decarbonization. One of the key areas driving innovation is the development of electric actuation systems for aircraft. As the trend towards More Electric Aircraft (MEA) gains momentum, aviation power systems developers are increasingly turning to these advanced technologies.
One of the latest advancements in this field is the introduction of integrated actuation power systems that offer high efficiency and low emissions. These systems are designed to be versatile, maintaining a consistent footprint regardless of the power output required. By integrating companion gate driver boards with Microchip’s HPD modules, a comprehensive motor drive solution is created for various aircraft systems, including flight controls, braking, and landing gear.
Leon Gross, vice president of Microchip’s discrete product group, highlighted the benefits of this integrated solution, stating, “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. With this solution, customers no longer need to design and develop their own drive circuitry, which can reduce design time, resources, and cost.”
These advanced power systems undergo rigorous testing to meet the stringent conditions outlined in DO-160 for airborne equipment. With multiple protection features such as shoot-through detection, short circuit protection, and active miller clamping, these systems ensure high reliability and safety in aviation applications.
Furthermore, the gate driver boards are designed to operate with external PWM signals based on Low Voltage Differential Signaling (LVDS) standards, offering low Electromagnetic Interference (EMI) and noise immunity. The boards provide telemetry outputs for monitoring critical parameters like DC bus current, phase current, and solenoid current, enhancing the overall efficiency and performance of the actuation systems.
