Intelligent power distribution system with a selectable output voltage
First Claim
1. An intelligent power distribution system capable of operating at a selectable output voltage, the system including a cable (1) with power bus conductors (1a, 1b) and an intelligent node (2) having a configuration and incorporating a controlled current switch (7) via which a power bus conductor (1a) is coupled to an output terminal (4) of the node (2) for supplying current to a load (5, 6) under control of the intelligent node (2), characterized in that between the controlled current switch (7) and an output line of the output terminal (4) is connected a converter (3) whose output voltage level is selectable by controlling the timing of the ON/OFF pulses of the controlled current switch (7), and the desired output voltage level is determined by the configuration of the intelligent node (2) and by messages received at the node (2).

Abstract
The present invention relates to an intelligent power distribution system capable of operating at a selectable output voltage, the system including a cable (1) with power bus conductors (1a, 1b) and an intelligent node (2) incorporating a controlled current switch (7) via which a power bus conductor is coupled to an output terminal (4) of the node (2) for supplying current to a load under control of the intelligent node (2). The effective value of the intelligent node output voltage is adapted settable by control of timing, or duty cycle, of the ON/OFF pulses of the controlled current switch (7).
