Standard for AC-to-DC and DC-to-AC Power Conversion To reduce aircraft emissions, developers are increasingly turning to more efficient designs that use electrical systems to replace the pneumatic and hydraulic systems that currently power on-board alternators, actuators and auxiliary power units (APUs).
Standards for AC-to-DC and DC-to-AC power conversion To reduce aircraft emissions, developers are increasingly inclined to adopt more efficient designs that use electrical systems to replace the pneumatic and hydraulic systems that currently power the on-board alternators, actuators, and auxiliary power units (APUs). To enable next-generation aircraft electrical systems, new power conversion technologies are needed. Microchip Technology Inc. today announced that it has worked with the Clean Sky Alliance, a joint European Commission (EC) and industry consortium, to develop the first aviation-compliant base-less power module designed to enable more efficient, lightweight and compact power conversion and motor drive systems.
Developed in partnership with the Clean Sky Alliance, Microchip's BL1, BL2 and BL3 series of baseless power modules improve AC-DC and DC-AC power conversion and generation efficiency by integrating silicon carbide power semiconductor technology to support stringent EU emissions standards and achieve climate neutrality in aviation by 2050. achieve the aviation industry's climate neutrality goal. Thanks to an improved substrate, this innovative design is 40 percent lighter than other comparable products and costs 10 percent less than standard power modules with metal backplanes. microchip's BL1, BL2 and BL3 devices meet all mechanical and environmental compliance requirements specified in RTCA DO-160G, Environmental Conditions and Test Procedures for Airborne Equipment, Version G (August 2010). RTCA is an industry consortium that sets rules on key aviation modernization issues.
The new series of modules are available in a low-profile, low-inductance package with power and signal connectors that designers can solder directly to a printed circuit board, helping to speed development and improve reliability. In addition, the modules in the series are identical in height to each other, allowing them to be paralleled or connected into three-phase bridges and other topologies to create higher-performance power converters and inverters.
Microchip's powerful new modules will help drive innovation in aircraft electrification and ultimately toward a lower-emissions future," said Leon Gross, vice president of Microchip's discrete products business unit. This is a new technology that empowers the systems that will usher in a new era of flight."
The modules employ silicon carbide MOSFETs and Schottky barrier diodes (SBDs) to maximize system efficiency. the BL1, BL2 and BL3 series packages are available from 100 W to 10 KW+ power in a choice of topologies, including phase leg, full bridge, asymmetric bridge, boost, buck and dual common source. These highly reliable power modules support voltages ranging from 600V to 1200V for silicon carbide MOSFETs and IGBTs, up to 1600V for rectifier diodes.
Microchip's power module technology and its ISO 9000 and AS9100 certified manufacturing facilities allow for high quality products utilizing flexible manufacturing solutions.
While introducing new innovations, Micrchip also works with system manufacturers and integrators on aging management to help customers minimize redesign efforts and extend lifecycles, thereby reducing total system cost.
Microchip is committed to providing designers with total system solutions for a variety of aerospace and defense applications. The base-less power module further complements Microchip's aerospace portfolio of motor drive controllers, memory integrated circuits, field programmable gate arrays (FPGAs), microcontrollers (MCUs), memory protection units (MPUs), timing products, semiconductors and point-of-load regulators. microchip also offers a complete line of Microchip also offers a complete line of silicon carbide technology solutions for aerospace, automotive and industrial applications.
Microchip's BL1, BL2 and BL3 baseless power modules output power specifications include 75A and 145A silicon carbide MOSFETs, as well as 50A IGBTs and 90A rectifier diodes.
