Abstract: Control systems and methods for independent control of power systems, particularly lighting network branches, and separate control of individual branch components. Multi-branch systems comprise independently controllable branches that inter-communicate via PLC communications. In each branch, components such as ballasts, local control units, sensors, actuators, and repeaters, may exchange commands and queries independently of a branch remote control unit (BRCU). Alternatively, a BRCU may manage or arbitrate communications, or interact with other BRCUs, other control units and external management systems. Ballasts include a multi-channel ballast that enables close-loop control of individual fixtures, or of individual dimmable or non-dimmable lamps within a fixture. The close-loop control is facilitated by sampling circuits/sensors co-located with each controlled fixture or lamp. All controllers are preferably implemented using an integrated digital controller.

Abstract: An integrated digital controller for controlling power electronic devices and method of its use, comprises an analog-to-digital converting scanner module for scanning analog data inputs and used to create digital data correlated with the analog inputs, a loop control module operative to receive the digital data ad used for controlling at least one control loop, and a pulse sequence generator (PSG) module used for generating a variety of fast, configurable, event-driven pulse sequences in cooperation with the PSG and scanner modules. The controller comprises optionally a CPU for managing various tasks and coordinate between the modules, means to create the events, and means for configuration and reconfiguration on-the-fly. The controller is preferably integrated in a semiconductor chip.
