UPS Reference Design Demonstrates Digital Power Advantages
Wed, 08/05/2009 - 10:44am
Microchip Technology's pure sine wave uninterruptible power supply (UPS) reference design is based on the dsPIC33F "GS" series of digital-power digital signal controllers. This reference design demonstrates how digital-power techniques, when applied to UPS applications, enable easy modifications through software, the use of smaller magnetics, intelligent battery charging, higher efficiency, compact designs, lower audible and electrical noise via a purer sine-wave output, USB communication, and a lower overall bill-of-materials cost. Though not available for purchase, all of the documentation, software, and Gerber files needed to build this reference design can be obtained for free from the company's website.
