摘要：
As a result of rapid development of LED lighting solutions and taking into account the new international regulations (Energy Star (R) and EN61000-3-2:2006) regarding the power factor, the power factor correction unit should be a compulsory component in any system that uses this kind of illumination. The present paper covers the concept, design, fabrication and testing of a lighting system composed of one major PFC unit and the individual drivers that deliver the power to the LEDs. This new star architecture has certain advantages over the conventional parallel one used at the present time, such as the power factor value, overall system efficiency and cost. The presented configuration is designed with the purpose to be used "as it is", with almost zero modifications on the existing electrical connections in most households or institutions. The system is designed for a maximum absorbed power of 2kW, but virtually any power limit could be achieved, depending on the specific requirements of the space to be illuminated.
