Title:
CENTRALIZED DEVICE FOR THE CONTROL OF THE FEEDING VOLTAGE OF A LOAD PROVIDED WITH A POWER FACTOR CORRECTION CONDENSER
Document Type and Number:
WIPO Patent Application WO2003069962
Kind Code:
A3
Abstract:
A centralized device for supply voltage control of a load with power factor correction condensers, in particular for lighting engineering applications, comprising a portion of power obtained by means of an array converter (15), which comprises in turn a plurality of switching means (16, 17),located between the network sinusoidal supply and the 5 load. According to the invention, said centralized device (14) comprises controlling and regulating means (18) for managing both the activation and deactivation states of the switching means (16, 17) of said array converter (15), so as to a void sudden voltage changes to the load and warrant control of continuous quantities of the load voltage.
