As the output current levels of power converters increase, interleaved topologies become widely used. A well-known topology is the interleaved buck converter (IBC), which presents as main characteristic an inherent low ripple output current source behavior in addition to high efficiency and small volume. At the same time, it is necessary to drive high-intensity discharge (HID) lamps with nearly constant current/power and low-frequency square-wave shape due to HID lamp voltage source characteristics and their acoustic resonance issue. This way, an IBC can be advantageous for supplying such lamps, particularly in high power levels where efficiency and volume become more critical parameters. The goal of this paper is a proposal of an electronic ballast based on a two-cell IBC for high-power HID lamps, with current control loop, voltage sensing, and constant power. A dc model based on averaged state-space technique is obtained for the ballast, as well as an ac model based on small-signal disturbances. A complete concept with a digitally implemented closed loop has been developed and a prototype has been built, successfully achieving performance targets. This paper describes the most relevant aspects of the complete design and presents results both experimental and from simulation in MATLAB/Simulink software.Index Terms-Closed loop, electronic ballasts, high-power highintensity discharge (HID) lamps, interleaved converters, modeling, state-space averaging technique.

“…The average value of voltage across the lamp must be zero, since it is also the voltage across the inductor. This leads to current average value being virtually zero also, since we are using an equivalent resistance model for the lamp, which is fairly true at high frequencies [7], [10]. Thus, the areas under each current half-cycle are equal.…”

The aim of this paper is to revisit the theme of nonresonant electronic ballasts focusing on a specific topology introduced in the last few years. Its complete mathematical analysis, which has not been fully explored in the past, and its practical implementation as a dc-fed electronic ballast unit is provided. The ballast here presented was successfully prototyped and is capable of pre-heating, igniting and driving two or more fluorescent light bulbs in series and has intrinsic protection against broken filaments and lamp absence. Furthermore, it relies solely on a single power switch and a relatively small-sized inductor per lamp, plus simple op-amp based control circuitry. An external protection circuitry is also presented in this paper, for protecting the power switch against lamp faulty conditions.

“…In this representation the inverter and the lamp are considered like only one resistance R INV , if an efficiency of the inverter of 100% is considered, then this resistance is the same that the lamp equivalent resistance. According to literature, there are several ways to stabilize the discharge arc in HID lamps; the two more commons are to feed the lamp with a power or current source [12], [16] and the use of impedance that limits the lamp current [13]. The simplest current limiter is a resistance, but it is the most inefficient solution.…”

This paper presents the design guidelines of electronic ballast for HID lamps. High efficient electronic ballast with high power factor and low THD (total harmonic distortion) is presented. The use of input current shaper converters (ICSC) working in Discontinuous-Conduction Mode (DCM) to stabilize the discharge arc in High Intensity Discharge (HID) lamps is proposed. The analysis of how the ICSC stabilizes the lamp current through the analysis of the output capacitor Co and model lamp is presented. The results indicated the feasibility to stabilize the lamp and obtaining high efficiency, high power factor and low THD in a single stage is presented.I.
