摘要： In a power-line-operated power-factor-corrected electronic ballast, a pair of series-connected fluorescent lamps is powered via a tuned L-C circuit that is series-excited by the rectangular-wave 33 kHz voltage output of a half-bridge inverter and parallel-loaded by the fluorescent lamps. Power factor correction is attained via two energy-storing capacitors charged during periods when the instantaneous absolute magnitude of the power line voltage exceeds half of its peak absolute magnitude and discharged when it fails to exceed half of this peak absolute magnitude. As a result, a so-called valley-filled DC voltage is provided to the inverter; which results in the inverter's rectangular-wave output voltage being about 50% amplitude-modulated. In spite of this high degree of amplitude-modulation, the resulting lamp current crest factor is only about 1.8. By control of the symmetry of the inverter's rectangular-wave output voltage, the fluorescent lamp is started and operated in such a manner that maximum available ballast output current is limited to about 30 milli-Ampere (which magnitude of 33 kHz current is considered safe from electric shock hazard) until such time as verification is provided to the effect that this 30 milli-Ampere of 33 kHz current is indeed flowing through both lamps (as opposed to through a ground loop); whereafter the symmetry of the rectangular-wave output voltage is re-controlled such as to provide for the lamp current to increase to some preset level.

摘要： A full-bridge transistor inverter is connected at its DC supply-side with an energy-storing capacitor. The inverter's output terminals are connected in series between a source of AC voltage and a load; which load may be an electric motor, a fluorescent lighting system, etc. By controllably switching the transistors of the inverter ON and OFF at some rate higher than, but basically synchronous with, the frequency of the AC voltage, effective control of the flow of power between the AC source and the load is achieved. DC voltage on the energy-storing capacitor is obtained from the AC source and established by way of the timing of the switching action of the inverter.Hence, in contrast with the ordinary situation where an inverter is supplied with net power from its source of DC voltage and where this net power is then supplied to a load connected with the inverter's output, the present invention relates to a situation where generally no net power is supplied to the inverter from its source of DC voltage and where generally no net power is supplied from the inverter's output. Instead, the inverter is used for controlling the waveform, magnitude and phasing of the alternating current flowing through it by way of its output terminals.

摘要： In a power-line-operated electronic ballast for a gas discharge lamp, an inverter converts a DC supply voltage to a high frequency current-limited operating voltage for a fluorescent lamp. The DC voltage is obtained, at least in part, by forward inductive-discharge conversion of full-wave-rectified unfiltered power line voltage; which forward conversion is accomplished by high frequency switching of an energy-storing inductor; the switching being done by the very same inverter that provides the high frequency lamp operating voltage. As an overall result, power is drawn from the power line with a power factor higher than 98% and with a total harmonic distortion under 10%.
