Modular connection between DC/DC converters is commonly used for many applications, to adapt voltage and power ranges, and in order to achieve scalability. This work presents a modular connection between DC/DC modules, providing an accurate voltage and power sharing, in a reliable way. This option could be used in the intermediate bus architectures, to adapt voltage and power levels, achieving high efficiency. Another advantage of the modular connection is the possibility of standardization. This way, it is possible to reuse a whole system module, just only adapting its voltage level, using an intermediate stage, based on the connection of several DC/DC blocks. To validate this solution, several DC/DC resonant converts have been designed for an input and output voltage of 56 V and 28 V respectively, for a rated power of 200 W (per module) and for a switching frequency of 400 kHz. Therefore, by combining several of these designed modules, it is possible to work at higher voltages and powers in whole system. |
