A battery-supplied, DC-HID lamp ballast, inspired on the Loss Free Resistor (LFR) concept is presented here. It consists of two stages. The first one, a boost converter, behaves like a constant power source. The second one, a switched capacitor boost converter is the ignitor circuit. The cascade connection of both converters results in a transformerless ballast able to reach a voltage of 6 kV from 12 V batteries. Among the ballast advantages we find: no light flickering, warm-up time reduction, no aging effects on lamp power, easy dimming control, and absence of acoustic resonance (AR) problems. The proposed system is compared with other existing solutions in the literature. After, the ballast dynamics, at both operation modes, is analyzed and simulated. The results achieved with one DC-HID lamp of 250 W demonstrate experimentally the feasibility of the proposed approach, where extreme voltage gains are achieved without a transformer. Besides of the expected functions of ignition and steady-state operation, the proposed circuit also includes other usual ballast features as diverse protections.Index Terms-Constant power, electronic ballast, high intensity-discharging (HID) lamps, sliding-mode control, loss-free resistor (LFR) and acoustic resonance (AR).

“…For application to indoor and outdoor lighting circumstances, the attractive features of high‐intensity‐discharge (HID) lamps are their high luminous efficacy, longer lamp lifetime and good colour rendering [1–5]. Although HID lamps have negative incremental impedance characteristics, a ballast is required to ignite the lamp during the start‐up transition and to supply rated power to the lamp during the steady‐state period.…”

This study presents a single-stage electronic ballast for the high-intensity-discharge (HID) lamp with high-power factor. The presented ballast consists of a discontinuous-conduction-mode operated dual-boost converter to achieve input current shaping, and a high-frequency combined with a low-frequency square-wave-driven half-bridge-type inverter for supplying the HID lamp with low-frequency square-wave sources. The attractive features of the proposed ballast are highpower factor (> 0.99), low total harmonic distortion of input utility-line current (< 10%), high efficiency (> 90%), costeffectiveness and freedom from acoustic resonance. The operational principles, design guidelines and a design example are included in this paper. A prototype ballast circuit has been successfully implemented and tested for supplying three different brands of 70W HID lamps operating with 110 V-root-mean-square input utility-line voltage. Satisfactory experimental results demonstrate the functionalities of the proposed ballast.

“…In the study reported here we describe the determination of the thermodynamic activities of the components in the condensed phases of the NaBr-DyBr 3 system. The data obtained are of fundamental interest (the chemistry of salts) and practical application (the development of metal halide lamps [12][13][14]). NaBr and DyBr 3 are possible components of the fill in metal halide lamps.…”
