Today's Relevance of Digital Control in Server- and Telecom Power Supplies

Today's Server- and Telecom Power Supplies (PSUs) in most instances have made the way through adopting digital control methods. This is enabled on the one hand by the high flexibility of digital control solutions, and on the other hand by competitive prices and performances of DSPs. This paper will present a depicted set of digital control solutions being in use in today's industrial environment. The presented methods are typically as well suitable for automotive power electronic applications, e.g. On-Board Chargers (OBC) and DC-DC converters, as well as for Server- & Telecom- Power Supply Units (PSU).
