First Aerospace-qualified Baseless Power Module Family Improves Aircraft Electrical System Efficiency
In the race to reduce aircraft emissions, developers increasingly are moving toward more efficient designs including electrical systems that replace today's pneumatics and hydraulics powering everything from on-board alternators to actuators and Auxiliary Power Units (APUs). To enable next-generation aircraft electrical systems, new power conversion technology is required. Microchip Technology Inc.announced its development with Clean Sky, a joint European Commission (EC) and industry consortium, of the first aerospace-qualified baseless power modules enabling higher-efficiency, lighter and more compact power conversion and motor drive systems.
Partnering with Clean Sky to support aerospace industry goals set by the EC for stricter emission standards that result in climate neutral aviation by 2050, Microchip's BL1, BL2 and BL3 family of baseless power modules provides greater efficiency in AC-to-DC and DC-to-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 produces an approximate 10% cost savings over standard power modules that incorporate metal baseplates. Microchip's BL1, BL2, and BL3 devices meet all mechanical and environmental compliance guidelines set forth in RTCA DO-160G, the “Environmental Conditions and Test Procedures for Airborne Equipment,” Version G (August 2010). RTCA is the industry consortium that develops consensus on critical aviation modernization issues.
The modules are available in low-profile, low-inductance packaging with power and signal connectors that designers can solder directly on printed circuit boards, helping to speed development and increase reliability. And, the same height between the modules in the family enables them to be paralleled or connected in a three-phase bridge and other topologies to achieve higher-performing power converters and inverters.
Microchip provides end-to-end design support to accelerate time to market including analysis, qualification and production. Designers can obtain numerous analysis and qualification reports on demand.
