Abstract
The utility model relates to a power transverter for a fluorescent lamp, comprising an input circuit, a rectifying filter circuit, a delayed trigger, an independent-excited push-pull oscillation circuit and an accumulated energy part. A capacitor is respectively arranged in the switch power tube of an oscillation circuit and the base emitting pole of an oscillation power tube to remove spike pulse. The utility model can ensure that the fluorescent lamp can be started and operated normally within the range of main power voltage from 100 volts to 260 volts. When started, the surge current of the filament of a fluorescent lamp tube is small; the service life of the fluorescent lamp tube can be effectively prolonged. Besides, the utility model has the advantages of quick startup, no strobo, no noise, no influence and no interference to human bodies and other electric apparatuses, etc.
Description
The utility model relates to electric power conversion apparatus, relates in particular to the fluorescent lamp power supply converter.
Had at present the circuit arrangement of many kinds control fluorescent lamps, and replaced old-fashioned Inductive ballast, had the unrivaled advantage of old-fashioned ballast, also have obviously energy-conservation, power factor is high, the advantage of no stroboscopic, rapid starter.But exist following shortcoming: (1) crosses when low or too high the fluorescent lamp cisco unity malfunction when supply voltage.(2) owing to have surge current, spike, easily cause the damage of power tube.
The purpose of this utility model is to overcome the defective of prior art, and a kind of fluorescent lamp power supply converter is provided.
The utility model is a kind of improvement to existing fluorescent lamp control, converting means.It is made up of input circuit, current rectifying and wave filtering circuit, time-delay trigger, independent-excited push-pull oscillator circuit and energy storage component.All be connected to an electric capacity between the basic emitter-base bandgap grading of switching power tube in the independent-excited push-pull oscillator circuit and hunting power pipe, to remove spike.And the preferred turn ratio of oscillation transformer, adjust frequency of oscillation, to reduce the generation of harmonic wave, avoided interference to other electrical equipment.Civil power changes direct current into through current rectifying and wave filtering circuit again through input circuit of the present utility model, and time-delay triggers, to avoid the triggering fluorescent lamp disadvantage of blackout easily too early.The utility model adopts two power tubes, makes vibration usefulness for one, and another is made switching tube and uses.
When line voltage in 100～260 volts of scopes, the utility model can guarantee still that fluorescent lamp is normal and start and work.During startup, little to the impulse current of fluorescent tube filament, can prolong useful life of fluorescent tube effectively.The utility model also has and starts rapidly, no stroboscopic, noiseless, the advantage that can not impact and disturb human body and other electrical equipment.
Fig. 1: be circuit diagram of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Magnetic core inductance L 1, L2 form input circuit of the present utility model altogether by two.Current rectifying and wave filtering circuit is made of bridge rectifier and the filter capacitor C1 that diode D3～D6 constitutes.Alternating current is received a pair of top of bridge rectifier and is carried out bridge rectifier after being total to magnetic core inductance L 1, L2, and another is to top cross-over connection filter capacitor C1, and output 300V direct voltage.Time-delay trigger is made of R1C2 integrating circuit and bidirectional trigger diode D2.The independent-excited push-pull oscillator circuit is made of diode D1, oscillating capacitance C5, oscillation transformer B, resistance R 2, R3, R4, R5 and power tube T1, T2.Power tube T1 is that switching tube, power tube T2 are oscillating tube.Cross-over connection has capacitor C 3, C4 respectively between the basic emitter-base bandgap grading of power tube T1, T2, to remove spike, improves the base stage waveform of power tube T1, T2, prolongs power tube useful life.The optimum valuing range of capacitor C 3, C4 is 80～120 to receive.
Direct current changes the superaudio sine wave into through oscillating circuit, for fluorescent lamp operation.The output of oscillating circuit is through energy storage component C6, and L3 meets fluorescent lamp G, and at fluorescent lamp G two ends and be connected to capacitor C 7, to reach the coupling purpose.The direct ground connection of the other end of fluorescent lamp G, load this moment plays shunting action to the hunting power pipe, has alleviated the burden of hunting power pipe, has prolonged its life-span.If the base stage wave-shape amplitude of oscillating circuit of the present utility model is too small, when low-voltage, can not start; If amplitude is excessive, easy burn-out power tube when high voltage therefore must the suitable turn ratio of selecting the every circle of vibration in the oscillation transformer.Because frequency of oscillation depends on the turn ratio of oscillator coil, frequency of oscillation is higher, and the harmonic wave of generation can disturb other electrical equipment, frequency of oscillation is on the low side, require holder stream circle body long-pending big, for this reason in view of above two aspects, the optimum range of the turn ratio of the coil among the oscillation transformer B is 1/4～1/3.
In order to reduce Q value widening frequency band, to guarantee energy matched well when line voltage changes on a large scale, improve the ability of the anti-high pressure of energy storage inductor high temperature resistance, the energy storage inductor L3 in the utility model adopts the coiling of multiply yarn envelope curve to form.
