Hybrid power drive module reduces weight in electric aviation, says Microchip
An integrated and configurable three-phase power module is the first variant of the new family released by Microchip which can be customised using silicon carbide or silicon, reducing power solution size and weight for electric aircraft.
It has been introduced to meet demand from 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. To meet the needs for an integrated and configurable power solution for aviation applications, Microchip Technology’s hybrid power drive module is the first variant introduced in the 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).
The hybrid power drive modules are integrated power semiconductor devices that reduce the number of components and simplify the overall system design, said Microchip. They also include 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 1,200V, with the option to customise up to 1,700V 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 PCB.
Microchip will provide detailed specification sheets and dedicated support from a knowledgeable engineering team member to help customers with every step of their design. The hybrid power drive modules are configurable with other Microchip products and parts, such as FPGAs, memory ICs, motor drive controllers and motor drive monitoring ICs.
The hybrid power drive module is available for order in production quantities- now.
