Microchip’s BL1, BL2 and BL3 families, developed with the Clean Sky consortium, meet strict aerospace standards for AC-DC and DC-AC power conversion

CHANDLER, Ariz., Aug. 03, 2021 (GLOBE NEWSWIRE) – In the race to reduce aircraft emissions, developers are increasingly moving towards more efficient designs, including electrical systems that replace pneumatic systems and hydraulic systems, powering everything from on-board alternators to actuators and auxiliary power units (APUs). To activate next-generation aircraft electrical systems, new energy conversion technology is required. Microchip Technology Inc. (Nasdaq: MCHP) today announced its development with Clean Sky, a joint consortium of the European Commission (EC) and industry, of the first aerospace-qualified baseless power modules enabling power conversion and drive systems more efficient, lighter and more compact engine.

In partnership with Clean Sky to support the aerospace industry targets set by the EC for stricter emissions standards that translate into climate neutral aviation by 2050, Microchip family of BL1, BL2 and BL3 power supply modules without base provides greater efficiency in AC-DC and DC-AC power conversion and generation through the integration of its silicon carbide power semiconductor technology. Forty percent lighter than others due to the modified substrate, the innovative design also saves around 10% in cost compared to standard power modules that incorporate metal base plates. Microchip’s BL1, BL2 and BL3 devices comply with all mechanical and environmental compliance guidelines set forth in RTCA DO-160G, “Environmental Conditions and Test Procedures for Airborne Equipment”, Version G (August 2010). RTCA is the industry consortium developing consensus on critical aviation modernization issues.

Modules are available in a compact, low-inductance package with power and signal connectors that designers can solder directly to printed circuit boards, helping speed development and increasing reliability. And, the same height between the modules of the family allows them to be paralleled or connected in a three-phase bridge and other topologies to obtain more efficient power converters and inverters.

“Microchip’s powerful new modules will help drive innovation in aircraft electrification and ultimately move towards a low-emission future,” said Leon Gross, vice president of the aircraft business unit. discreet products from Microchip. “This is a systems enabling technology ushering in a new era of flight.”

The family incorporates silicon carbide MOSFETs and Schottky barrier diodes (SBD) to maximize system efficiency. In packages delivering 100W to over 10KW of power, the BL1, BL2 and BL3 family is available in many topology options including phase branch, full bridge, unbalanced bridge, boost, buck and the common dual source. These high reliability power modules are available in voltage ranges from 600V to 1200V in silicon carbide MOSFETs and IGBTs up to 1600V for rectifier diodes.

Microchip’s power module technology along with its ISO 9000 and AS9100 certified manufacturing facilities deliver high quality units through flexible manufacturing alternatives.

While introducing new innovations, the company is also partnering with system manufacturers and integrators on obsolescence management, supporting customer efforts to minimize redesign work and lengthen lifecycles, thereby reducing costs. overall system costs.

The company’s baseless power modules complement its aerospace portfolio of motor drive controllers, storage integrated circuits, field programmable gate arrays (FPGAs), microcontrollers (MCUs), microprocessors (MPUs) , timing, semiconductor and point-of-load regulator products – providing designers with complete system solutions for a wide variety of aerospace and defense applications. Microchip also offers a full line of silicon carbide technology solutions for aerospace, automotive and industrial applications.
