Microchip unveils hybrid power drive module

Microchip Technology Inc. has introduced an all-on-one hybrid power drive module for electric aircraft. It is the first variant in a new product line of power devices that will be available in 12 different variants with either silicon carbide (SiC) MOSFETs or insulated-gate bipolar transistors (IGBTs).

Targeting aircraft manufacturers that are designing more electric aircraft (MEA) to convert hydraulic flight control systems to electric, the new hybrid power drive modules are designed to reduce the size and weight. These modules are highly integrated power semiconductor devices that reduce the number of components and simplify the overall system design, said Microchip, and the configurable power devices include a three-bridge topology that are available in SiC or Si semiconductor technologies.

The power modules enable high-switching frequency power generation for smaller and more efficient systems. They are also designed for low inductances for high-power density with power and signal connectors that are soldered directly on the printed circuit board.

The standard voltage of the power modules ranges from 650 V to 1200 V, with the option to customize up to 1700 V on request. Optional add-on capabilities include soft start, solenoid interface drive, regenerative brake switch and thermal sensors for external monitoring circuitry usage. They offer numerous auxiliary power devices that enable an inrush current limit function, said Microchip.

These hybrid power drive modules are configurable with other Microchip products and parts, such as field-programmable gate arrays (FPGAs), memory integrated circuits, motor drive controllers and motor drive monitoring integrated circuits. The hybrid power drive module is available now in production quantities.
