Microchip Launches New All-in-One Hybrid Drive Module Solution Designed for Electric Aviation Applications

Microchip introduces new all-in-one hybrid drive module solution designed for electric aviation applications, reducing development time and weight

The first in a new family of products, this highly integrated and configurable three-phase power module can be customized using either silicon carbide or silicon, reducing the size and weight of electric aircraft power solutions

Aircraft manufacturers designing more electric aircraft (MEA) want to convert flight control systems from hydraulic to electric to reduce weight and design complexity. To meet the demand for integrated and configurable power solutions for aviation applications, Microchip Technology Inc. (Microchip Technology) today announced a new comprehensive hybrid drive module, the first model in a new power device product family. The family will have 12 different models using silicon carbide (SiC) MOSFETs or insulated gate bipolar transistors (IGBTs).

These hybrid drive modules are highly integrated power semiconductor devices that reduce component count and simplify overall system design. This configurable family of devices includes a three-bridge topology and can use either SiC or Si semiconductor technology. The new family of devices is highly reliable, compact and lightweight, helping to reduce the size and weight of more electric aircraft.

Other key features of these hybrid drive modules include a rich set of auxiliary power devices to facilitate inrush current limit functions. Optional additional functions also include soft start, solenoid valve interface drive, regenerative braking switch and thermal sensor for external monitoring circuits. These drive modules can also achieve high switching frequency power generation, making the system smaller and more efficient.

The power module has a standard voltage range of 650 V to 1200 V and can be customized up to 1700 V upon request. The device features a low inductance design that enables high power density, and the power and signal connectors can be soldered directly onto the user's printed circuit board.

“Microchip is committed to providing the aviation industry with cornerstone products that will enable the industry to deploy lighter, more compact and more efficient system solutions,” said Leon Gross, vice president of Microchip’s Discrete Power Management business unit . “The hybrid drive module will provide a comprehensive power solution for customers designing more electric aircraft.”

Microchip is a mature supplier of comprehensive power solutions in the industry. These hybrid drive modules can be easily configured with other Microchip products and components, such as field programmable gate arrays (FPGAs), memory integrated circuits, motor drive controllers and motor drive monitoring integrated circuits.

Development Tools

Microchip will provide detailed specification sheets and professional engineering team support to help customers in every aspect of the design.
