“…Controlling the current with a fast response control system/ mechanism can prevent painful stimulation of the deeper tissues. Similar control schemes are used in the ballasts of arc lamps to limit the current rapidly to compensate for the rapid drop in the resistance (from the megaohm range to the few ohm range) of the lamp after the arc formation 25 .…”

“…Unfortunately, there is a serious problem of acoustic resonance when the HID lamps operate in a certain frequency range. 2,3 For electronic HID lamp operation to avoid acoustic resonances, low frequency square wave (LFSW) is the preferred method. This type of ballast is more widely developed and used in many applications.…”

In this paper, the dimming effects on the photometric and electric characteristics of high intensity discharge lamps supplied by a low frequency square waveform are evaluated. For this evaluation an electronic ballast is presented. The ballast consists of a current source, AC/DC converter and a full-bridge inverter. The electronic supply provides to the lamp a different form of current excitation (square waves with variable short drops). Dimming control and the characteristics of low frequency operated high intensity discharge lamps are described. The lamp is represented in a simulation by its conductance model and coupled to its electronic power supply. Experimental results are shown and compared with the simulation. A dimming range from 100% to about 60% has been achieved.

“…Another problem to develop electronic ballast for High Intensity Discharge (HID) lamps is the presence of the acoustic resonances phenomenon. This phenomenon consists in discharge arc fluctuations that cause variations in the emitted light and the power delivered to the lamp [1], [2]. Several solutions has been proposed to eliminate this phenomenon.…”

“…The principal control strategies for Power Factor Correction (PFC) converters are "Resistance emulator" [1], [10], [11] and "Loss-Free Resistor" [4], [9], these techniques require a constant DC output voltage. This means that in order to achieve a constant DC output voltage, large capacitance values are required.…”

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.
