Abstract :
In the following years power levels of 10 kW to 100 kW will be demanded by the telecommunication satellites. The reason for it is that the geostationary orbit required by this kind of satellites is becoming too crowded. It is not possible to keep 0.5 kW modules with more than 100 in parallel and therefore higher power modules must be used. A higher bus voltage seems also necessary and any voltage below 150 V and above 100 V could meet the needs. In this article, design guidelines and experimental results of a current doublet ZVS topology with parallel power processing to obtain a high efficiency battery discharger unit are given
