Abstract :
Today, energy saving is one of the main objectives for engineers. In the case of mobile applications, energy can be saved by two different ways. First, decreasing the total masse of the system, and second, increasing the efficiency of the overall system. This paper presents an optimization strategy to design an interleaved DC/DC converter in order to find the best compromise between efficiency, weight and current inductor ripple. The strategy of this method also lends itself well to find the right split power level that must by selected to obtain the best efficiency and weight power density of a given application.
