This paper addresses two converging trends: digital control and management of power conversion systems; and recognition of the importance of energy conservation. It is shown that the use of digital techniques can increase the efficiency of power supplies and the systems that use them. Efficiency, in turn, is the primary driver for energy conservation—optimization of efficiency leads to the concept of Energy Management, rather than "power management." The relationship between increased power supply efficiency and quantifiable measures of energy conservation is explored.
