Modular bidirectional bus system for exchanging energy between modules

摘要

A modular bidirectional bus system (1) for exchanging energy between modules (21-25). The system is provided with at least one bus (2) and a plurality of exchangeable modules which are detachably connected with the bus for mutually exchanging electric energy between the modules via the bus. The system is arranged such that the modules operatively generate a voltage on the bus which is within a predetermined voltage interval.
