Contributors to EE Times' October 13th InFocus section on "Backplane power management" described several different methods of buffering the power supplies on a circuit card from surges on a card cage backplane. We were particularly struck with Summit Microelectronics's overview of the processes used to monitor and control on-board voltages and current rushes. Their overview, digested for the InFocus section, stressed the issue of maintaining fail-safe operation. The article actually offered appl

Safety concerns for practical EMI line filters
News & Analysis 10/21/2003 Post a comment
When we design EMI filters, we will find that safety issues, thermal issues, and even loop stability concerns are intricately linked with the central issue of EMI, writes National's Sanjaya Maniktala in the third chapter of this book-length series. Hypothetically speaking, we can put up for sale almost product that doesn't perform properly, however product safety is a legal requirement, without which we cannot sell. In off-line applications and high-voltage DC-DC converters, where the voltages a
