With aircraft manufacturers designing More Electric Aircraft (MEA) and looking to convert the flight control systems from hydraulic to electric to reduce weight and design complexities this module looks to meet the needs for an integrated and configurable power solution for aviation applications.
This first variant in the new product line of power devices will be one of 12 different variants with either silicon carbide (SiC) MOSFETs or insulated-gate bipolar transistors (IGBTs).
These hybrid power drive modules are highly integrated power semiconductor devices that reduce the number of components and simplify the overall system design.
The configurable power devices include a three-bridge topology that are available in SiC or Si semiconductor technologies. Offering a compact design and low weight and profile, these high-reliability power devices help reduce the size and weight of MEAs.
Other key capabilities include numerous auxiliary power devices that facilitate an inrush current limit function. Optional add-on capabilities include soft start, solenoid interface drive, regenerative brake switch and thermal sensors for external monitoring circuitry usage. The power modules also facilitate high-switching frequency power generation, which enables smaller and more efficient systems.
The standard voltage of the power modules ranges from 650V to 1200V, with the option to customise up to 1700V on request. The device is designed for low inductances for high-power density with power and signal connectors that are solderable directly on the user’s printed circuit board.
