“…In this manner it is often possible to use resonators as so-called ballasts to avoid plasma instability such as the glow-to-arc transition [2]. This principle is used in plasma lighting circuits [3,4], RF capacitively-and inductively-coupled plasmas [5,6], and many microwave plasmas [7]. As a counter-example, quasi-optical microwave beams that are focused with dielectric lenses or concentrating reflectors are essentially without ballast and result in interesting streamer formation [8].…”

Arrays of dielectric resonators-illuminated by an antenna-are used to ignite and sustain multiple microwave plasmas in parallel. Calcium titanate cylindrical resonators were arranged in a linear array with separation distances between 0.5 and 5 mm. The operating frequency was near the HEM 111 resonance of 1.1 GHz. Paschen curves of the breakdown field and voltage in argon atmosphere are consistent with parallel plate microwave breakdown except within discharge gaps of 1 mm or less. Sustaining of argon plasma between 0.5 Torr and 1 atm within the array is found to alter the electromagnetic scattering from the dielectric resonators, suggesting applications in plasma-reconfigurable metamaterials and photonic crystals.

“…In order to eliminate the transformer at the ballast output, which is generally used with PFC Boost converters the voltage regulation via the inverter is proposed. Same examples PFC boost converters can be found in [3], [11], [16], [25], [28].…”

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

“…According to IEC 662: the voltage level that guarantees HPS 70 W lamps ignition should be between 1.8 kV and 2.5 kV [13]. However, HPS lamp ignition, by means of an LCC resonant circuit, can be achieved with much lower voltage levels [14], [18] and [19], what is attributed to the occurrence of high frequency repetitive high voltage pulses (pulsation phenomenon) [13].…”

This paper describes the analysis and design of an electronic ballast devised to drive both, high pressure sodium vapor (HPS) and high pressure mercury vapor (HPMV) lamps, in dimmed operation with no need of parameter modification. The main objective is to achieve weight and volume reduction of a public lighting components bench test equipment, used to perform basic operational tests in a Brazilian electric utility company. Specifically, the analysis, design and implementation of an electronic ballast, based on a series-parallel loaded resonant inverter, for 70 W HPS and 125 W HPMV lamps testing is presented. Experimental results from a lab prototype, performing high intensity discharge (HID) lamp tests in dimmed operation and no discharge arc instability, evidences the feasibility of the proposed ballast concerning the intended application.
