An improvement in the current fed parallel resonant half bridge (CFPRHB) circuits used in fluorescent lamp electronic ballasts is provided in this paper. The CFPRHB belongs to the self-oscillating family which includes the current fed push-pull and series resonant inverters, most of which are used in instant-start applications. However, many failure modes are related to the bypass capacitor according to an analysis of failed samples. In this paper, the operating functions of the existing topology in the steady state are analyzed and the main root cause of failure modes has been found. Comparisons between the two topologies are conducted in terms of the voltage stress of the bypass capacitor as well as the thermal and performance of the ballasts to verify the advantages of the proposed topology. It is found that the improved topology is capable of enhancing the reliability and reducing the cost of products without having a negative influence on the system performance.

“…For example, fluorescent lamps need to be driven by a source that features high output impedance to stabilize their operating point [4], and by high frequency signals to increase their light output. That is, a fluorescent lamp driver must feed the lamp with a constant current that will be independent of the lamp resistance.…”

Abstract-Here, a high frequency AC current-sourcing driver that can feed electrical loads with a constant current independent of the load resistance is presented, analyzed and tested experimentally. The power source is a self-oscillating inverter that includes a resonant network and a Current Comparing and Toggling Circuit (CCTC) that is used to generate the control signals of the inverter's power switches. The power driver can be used to ignite and operate one or several serially connected fluorescent lamps, without the need of additional resonant networks and redesign of the power stage, while still maintaining high efficiency and low output crest factor. The CCTC is realized, in the present work, by a multi-winding transformer that is designed to change the polarity of the gate drive of the power switches whenever the input signal drops to the level of the desired output current and hence, will cause the driver to behave as a current source.

Abstract-A novel HF multiresonant ballast for fluorescent lamps is analyzed, simulated, and tested experimentally. The ballast includes two major resonant networks. The lamp is driven by a parallel resonance arrangement that acts as a current source. During warm-up the filaments are driven by a secondary winding of a series-resonant inductor. The series resonance branch, which is active during warm-up, feeds the filament and shorts out the voltage across the lamp. Simulation and experimental results suggest that the inherent features of the proposed ballast topology will prolong lamp life.Index Terms-Electronic ballast, fluorescent lamps, resonant inverter, SPICE simulation.
