Abstract

Distributed power systems architectures have been proposed as an optimal choice for many telecommunication applications. In these architectures, the DC/DC conversion stage is an on-board converter with very hard specifications in terms of efficiency and size. Some of the most usual specifications for telecom on-board DC/DC converters are considered, and the most suitable topologies are reviewed for each case. Pulse width modulated (PWM) quasi- and multiresonant topologies are taken into consideration and comparative analysis is performed from the point of view of size, efficiency, reliability and EMC behavior
