Abstract-A new self-adjusting current-fed push-pull parallel inverter (SA-CFPPRI) is presented and tested by simulation and experimentally. The power source includes a soft switching control circuitry and a controllable inductor. The SA-CFPPRI can drive a capacitive load at any frequency within the design range. It will maintain zero voltage switching of the main transistors and follow the input frequency signal even when the resonant elements and/or the load vary. Possible range of applications for the proposed power source is: piezoelectric transformers and motors, ac bus for a distributed power system and other loads that need to be fed by a sinusoidal waveform. The experimental results of the laboratory unit (160 Vrms at 93 kHz and nominal output power of 5 W) verify the analytical analysis and proposed design procedure.Index Terms-Phase comparator, push-pull parallel resonant inverter (PPPRI), sinusoidal power source, variable inductor.

“…In recent years, electronic ballasts have attracted much research interest [1]- [15] due to the merits of high-frequency ballasting, such as high efficacy, low audible noise, long lifetime, unnoticeable flickering, small volume, and light weight. At present, push-pull [4], [8]- [11] or half-bridge [5]- [7], [12] series-parallel resonant inverters have been employed for electronic ballasts. Nevertheless, based on the considerations of cost and reliability, most off-line electronic ballasts adopt self-oscillating half-bridge inverters.…”

Steady-state analysis and simulation of a BJT self-oscillating ZVS-CV ballast driven by a saturable transformer

The steady-state oscillation of a zero-voltageswitching clamped-voltage self-oscillating ballast driven by a saturable transformer is analyzed and simulated. Its selfoscillating operation is divided into six stages according to the hysteresis B-H loop of saturable transformer cores. Stage-wise circuit analysis shows the saturable transformer limits the lamp current and dominates the switching frequency of the ballast. The saturating behavior of driving and switching devices clearly distinguishes this self-oscillating inverter from an external-drive high-quality-factor resonant inverter. Analytical results are verified by mathematical simulation and laboratory experiment.

“…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.
