摘要： Disclosed is a low-cost parallel lighting system for discharge lamps for a surface light source, which reduces nonuniform brightness and static noise, and fulfills a requirement that lamp currents of individual cold-cathode fluorescent lamps should be uniform and stabilized. In a surface light source system having multiple discharge lamps, there is a module which lights the discharge lamps in parallel and whose input terminal and electrodes on an opposite side to that side of the discharge lamps which is connected to the module are driven by voltage waveforms different in phase by 180 degrees from each other, wherein an input terminal of an opposite phase of the surface light source system is connected to an inverter circuit having outputs of opposite phases via a single shunt transformer in such a way as to cancel out magnetic fluxes generated by currents respectively flowing in windings of the shunt transformer, whereby the resonance frequency of the inverter circuit having outputs of opposite phases is matched to balance the outputs.

摘要： A circuit arrangement for operating a high pressure discharge lamp comprising a DC/DC down converter which provided a DC current to an output capacitor (Cout), the output capacitor (Cout) being connected in parallel to a full bridge inverter (S1-S4). The current provided by the DC/DC converter is regulated via a control circuit (CSG) which renders alternatively conductive and non-conductive a switching element (Sd), in dependency of the amplitude of the voltage across the output capacitor (Cout). In particular, a reference signal (Sref) indicative of the DC current to be supplied by the DC/DC converter, is periodically modulated at each commutation of the full bridge inverter (S1-S4) by a microprocessor (μP) in dependency of the peak voltage detected on the output capacitor (Cout) by a peak detector (PD). Consequently, it can be achieved a reduction of resonance phenomena between the output capacitor (Cout) and the component of the full bridge converter such as the ignition choke (Lign) and/or the lamp (LA).

摘要： An electronic device for powering a fluorescent lamp (16) starting from a sinusoidal alternating voltage comprises a whole-bridge rectifier (12) which rectifies the alternating voltage, a circuit (13) for processing the rectified voltage connected in parallel to the output of the rectifier (12) and a half-bridge inverter (14) with an output (D) for high frequency powering of the lamp (16). The processing circuit has a direct voltage output (A-C) at the ends of a bulk capacitor (CB) connected in parallel to the output of the rectifier (12) through a first diode (DP). A resonant network (17) to which is connected the lamp (16) is connected between the output (D) of the half-bridge inverter (14) and an intermediate point (B) of a series of two capacitors (CP1,CP2) connected in parallel to the output of the rectifier (12). The circuit allows obtaining with simplicity a power factor near unity and a limited lamp current crest factor.
