Electronic control of a multi-phase lighting system

In the paper, the dynamic model of a lighting system is taken into account and a simple control strategy for controlling the load voltages is presented. All the main components of the electronic system (supply, rectifier, capacitive filter, inverter, etc.) have been modelled in details by using the graphical modelling technique named Power-Oriented Graphs. A control strategy for minimizing the neutral current iN is also presented. Simulation results show the effectiveness of the presented control strategies.
