Description

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a charging pump type electronic ballast, and more particularly to a charging pump type electronic ballast having a piezoelectric transformer. [Prior Art] With the advancement of technology and the development of the economy, the demand for switching converters has increased. Conventional gas discharge lamps have the characteristics of negative incremental resistance, so it is necessary to use a suitable electronic ballast to make it work stably. In recent years, due to the great advancement of power electronics technology, electronic ballasts have gradually replaced traditional electromagnetic ballasts. In addition to the thin and light design, the luminous efficiency and illumination quality of fluorescent lamps have been further improved. The electronic ballast needs to provide a sufficiently high lighting voltage at the transient moment of starting; when the electronic ballast is operated at steady state, it needs to provide a stable current to the fluorescent tube to provide the rated lamp power.俾 to maintain the luminous quality of the gas discharge lamp. The power supply used in a typical switching converter is direct current. However, the power supply currently supplied by the power system is alternating current. Therefore, most of the current use of a two-pole full-wave rectifier circuit converts the alternating current power supplied by the power system into direct current. For use with switching converters. Therefore, in order to eliminate the rectified AC component, a large capacitor is often connected in parallel with the rectifier circuit to obtain a stable DC voltage. However, it is because this capacitor maintains the DC voltage at a fixed level, so that the rectifier can only be turned on when the amplitude of the AC voltage is higher than the capacitor voltage, and the required power is drawn from the power supply. Therefore, the rectifier is turned on very short during each input power cycle in 200824502, and there is a large inrush current during this period. Inrush currents appear in the form of spikes near the peak of the AC supply voltage. These current waveforms contain high harmonics (Harmonic) and produce low power factor non-impedance at the AC source. The reduction in power factor not only reduces the profit factor of the power equipment (such as the transformer) in the system, but also forces the relevant components and equipment to have a rated capacity to supply the load. In addition, the high-order spectral current f causes malfunction of the control circuit and the power protection device, and the measurement instrument or the communication system is disturbed, and the waveform of the power supply voltage is affected to cause distortion. In order to improve the low power and high spectral currents caused by the rectifying and filtering circuit of the electronic ballast to the power system (4), most of the conventional methods (4) charge pumping architecture as a power factor corrector, and applied to the resonant tank In the electronic ballast, the main purpose of the resonant tank is to allow the square wave voltage switched by the inverter to pass only the fundamental frequency component and attenuate the higher harmonic components, so that the resonant tank output can obtain a flat AC string. wave. Referring to Fig. 1, there is shown a circuit schematic of a conventional electronic ballast. As shown in FIG. 1, the front stage circuit is a rectifier 11 〇 for supplying a DC voltage to the subsequent stage circuit, and the latter stage circuit is a resonant circuit ι ΐ 2 and an inverter 114 for providing a stable sine wave voltage to the load. 116.
