“…This type of ballast is more widely developed and used in many applications. 4,5 Feeding HID lamps with square waveform current has a better result [6][7][8] than sinusoidal waveforms. The electronic ballast structure developed in this work presents several advantages.…”

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.

“…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.

“…Revised on 16/01/2013 and on 25/02/2013. Accepted for publication in 25/02/2013 to Special Session by recommendation he Editor Ricardo Nederson do Prado whenever the acoustic resonance is detected which implies in methods for detecting it [10], [11], [12]; third, even when operating the ballast in frequencies where acoustic resonance occurs, to avoid exciting it through spreading the frequency spectrum [13]- [21], [28]. Each and every one of these alternatives has its advantages and drawbacks as will be pointed out further.…”

The modulation index control is used in this work to control the lamp power supply permitting the removal of the output transformer out of the inverterresonant filter setup. The Acoustic resonance in HPS lamps can be avoided by using a controlled PWM inverter and third harmonic injection.Experimental and simulation results are shown for the control of the inverter power subject to variation in the input voltage. Results for different DC bus voltages are also provided which attest the transformer removal and avoid the acoustic resonance with different modulation indexes. An ignitor for high-intensity discharge lamps, based on forced oscillation via an external periodic voltage square wave, supplied by a digitally controlled inverter, is also presented. The crest factor of the current can also be reduced by this approach.1
