PULSE BALLAST FOR PLANAR LIGHTS

摘要

The invention relates to an electrical circuit for supplying power to a pulsed discharge light, comprising two switching arms, a light arm, and two power supply arms, placed in the following manner: (a) the first and second switching arms each comprise a switch (X1, X2), a self-inductor (L1, L2), and a diode (D1, D2) so that, in each switching arm, (a) the switcher (X1, X2) is parallel to the diode (D1, D2) and in series with the self-inductor (L1, L2); (b) the lighting arm includes two terminals connectable to a discharge light (EL), one of said terminals also being connected to the common point of said first and second switching arms, the other also being connected to the two power supply arms; and (c) the power supply arms each include a voltage supply (V1, V2) that charges a capacitor (C1, C2), said voltage supplies (V1, V2) being placed in series with, and the common point thereof being connected to, the lighting arm.
