Below enumerate one and state fluorescent lamp circuit design example explanation the utility model.
As shown in Figure 2, described fluorescent lamp circuit comprises that divider resistance FS, diode D1~D4 form full-wave bridge rectifier circuit, be connected in the electrolytic capacitor CE1 of full-wave rectifying circuit two outputs, the active half-bridge branch road that comprises triode Q1, triode Q2 and magnetic ring transformer T, fluorescent tube is in series as load and inductance L 1, is connected across between two half-bridges.Its course of work is as follows:
Described four diode D1, D2, D3, D4 form full-wave bridge rectifier circuit alternating voltage (frequency is 50/60HZ) are converted to the dc pulse moving voltage VCE1 on the electrolytic capacitor CE1.Electrolytic capacitor CE1 plays the usefulness of smothing filtering, and its capacitance is big more, and this voltage VCE1 is level and smooth more, and more near direct voltage E, the supply power voltage of half-bridge inversion circuit is also stable more.
Triode Q1, Q2 form active half-bridge branch road, and the mid-point voltage of half-bridge is half of direct voltage E, is E/2, and fluorescent tube is in series as load and inductance L 1, are connected across between two half-bridges.After adding power supply, the electric current that is provided by dc pulse moving voltage VCE1 charges through 1 couple of integrating capacitor C3 of resistance R, in case this voltage meets and exceeds the breakover voltage of diac DB3 (after about 30~40V), this diode DB3 punctures conducting, and there is electric current to flow into the base stage of triode Q2, make triode Q2 conducting, at this moment, electric current is flowed through successively: the collector electrode of elementary winding N2, the triode Q2 of electrolytic capacitor CE1, capacitor C 4, fluorescent tube filament, inductance L 1, magnetic ring transformer T.
Along with the increase of triode Q2 collector current ic2 and the decline of magnet ring permeability, the situation that voltage VN2 on the magnet ring winding is lower than triode Q2 base voltage VB2 can appear, make base current reverse, triode Q2 base current ib2 becomes negative value, rely on this reverse current, the unnecessary electronics in base is disappeared, triode Q2 withdraws from from saturation condition, enter magnifying state, in case enter magnifying state, the decline of current i c2 reduces ib2 by the positive feedback of magnet ring, ib2 further reduces, the very fast saltus step of triode Q2 is for ending, and meanwhile, the voltage on the magnet ring winding N1 changes limit polarity, on negative just down, after having postponed a period of time, Q1 has electric current to produce, and will produce induction kinetic potential opposite when increasing with ic2 in the magnet ring voltage device and form chain reaction.
Said process repeats to go earlier again and again, triode Q1, Q2 take turns conducting with end, between two half-bridge mid point, form the square-wave voltage of alternation, its amplitude is that (voltage of active half-bridge mid point drops to 0 by E to E/2, be E by 0 saltus step again later on, and the voltage of passive half-bridge mid point is E/2).This alternating voltage is through starting capacitor C 5, series resonance effect on the inductance L 1, its electric current becomes near sinusoidal wave, and (it is worth and the Q value and capacitor C 5 values of inductance L 1 determine) is added on the fluorescent tube to have produced a very high voltage at capacitor C 5 two ends, thereby lamp lighting-up is lighted.
