“…El inversor es alimentado con corriente y se implementó con una configuración push-pull con transformador, que se autoajusta a la frecuencia de resonancia, paralelo del circuito formado por el transformador elevador T1 y la celda de descarga DBD. El control se implementó mediante el circuito UC3872 de Texas Instrument [3,19,20]. El hardware del controlador está basado en un DSP TMS320F2812 de texas instrument, el cual ejecuta el algoritmo que controla el convertidor buck.…”

The ozone generation systems generally use the pulse amplitude modulation (PAM) to vary or control the ozone concentration. The results obtained after the implementation of pulse density modulation (PDM) in the power supply system of an ozone generation and the improvement achieved in the efficiency curve is presented in this paper. PAM and PDM techniques were applied in ozone generation system with push-pull inverter resonant self. The adjusted voltage amplitude of the PDM waveform power is determined from the condition of the PAM waveform where the maximum efficiency was obtained; Thus achieving increased efficiency in 60% of operating points ozone generation system.

“…1). Pushpull converters have being used for a long time [7]- [11]. The reasons for using this type of converter in photovoltaic applications are: (1) it can be used for both grid connected or isolated systems, (2) it can operate with or without a battery bank, (3) it provides galvanic isolation, (4) it allows a high voltage gain and (5) it has a high power density.…”

An active control law for a current fed push-pull converter used in photovoltaic applications is discussed in this paper. The proposed control law aims at avoiding magnetic flux saturation and eliminating the magnetic flux imbalance observed at both windings of the converter transformer. The most prominent advantages of operating without flux saturation are: a more effective magnetic core design; power switches and converter live endurance; less voltage switching stress. Detailed analysis including simulation and experimental results are used to demonstrate the effectiveness of the proposed active control law.

“…Several types of loads need to be driven by a constant ac current in order to optimize their performance and maximize the system's efficiency [1] - [3]. 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.…”

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.
