Microchip has combined gate driver boards with its Hybrid Power Drive (HPD) modules to ease the aviation industry’s transition to electric actuation systems. Configured with silicon or silicon carbide switches, the HPD modules cover a range of 5 kVA to 20 kVA and maintain the same footprint regardless of the power output.
These integrated actuation power bundles provide a plug-and-play motor drive solution for the electrification of such systems as flight controls, braking, and landing gear. Power components are designed to scale based on application requirements. They can be used to create actuation systems for drones, small planes, electric vertical take-off and landing aircraft, More Electric Aircraft (MEA), and all-electric aircraft.
Gate driver boards are driven with external PWM signals. They provide differential outputs for telemetry signals like DC bus current, phase current, and solenoid current by taking feedback from shunts in the HPD modules and DC bus voltage. The isolated boards operate over a temperature range of -55°C to +110°C and require a single 15-VDC input for the control and drive circuit. Additional required voltages can be generated on the card.
The gate driver boards and accompanying HPD modules are available now in production quantities. To learn more about these integrated actuation power components, click here.
