摘要
The demand for decreasing cost and volume and also for increasing efficiency leads to a constantly increasing power density of converter systems. For maximising the power density of a 5kW telecom supply an optimisation procedure that automatically balances the switching frequency, semiconductor and passive losses, and thermal performance has been developed. This procedure and the belonging analytical converter and transformer models are presented in this paper. Moreover, the resulting optimised design, which has a power density of 10kW/ltr. and an efficiency of 96% at a height of 1U, is presented.
