“…The previous one, presented in [8] is called BiFlyback Integrated Ballast with Current Stress (BFIB-CS), and the proposed one is BiFlyback Integrated Ballast with Voltage Stress (BFIB-VS). It can be observed, from Figure 1, that both topologies have the same number of components with similar voltage and current characteristics with the exception of the shared switch (S 1 ) and diodes D 5 and D 6 .…”

“…When High Intensity Discharge (HID) lamps are supplied by high frequency sinusoidal current waveforms, they are susceptible to the occurrence of the acoustic resonance (AR) phenomenon [1]. In literature, many works have studied this phenomenon and different methods have been proposed in order to avoid its occurrence [2] - [6].…”

This paper presents a simple configuration, based on the integration of two flyback converters, to supply high intensity discharge (HID) lamps with a low frequency square waveform (LFSW), in order to avoid the occurrence of the acoustic resonance (AR) phenomenon. The proposed topology is compared to a previous presented one. Both topologies integrate two flyback converters in different ways. Losses of both integration modes are compared and advantages are discussed in respect to current and voltage components stress. The proposed electronic ballast presents a high efficiency with a reduced number of components and no over current stress in the shared switch. Experimental results validate both configurations.
