Performance comparison of four practical implementations based on PWM, quasi and multiresonant topologies for on board DC/DC converters in distributed power architectures

Abstract

In distributed power system architectures, the DC/DC conversion stage turns out to be an onboard converter with very stringent specifications, particularly in terms of efficiency and size. Practical implementations of four DC/DC converters based on PWM, quasi-resonant, and multiresonant topologies are compared for a telecommunications onboard application. Experimental results concerning efficiency, component stresses, EMC behavior and size are provided, and a comparative analysis based on these data is performed.<>
