Abstract
The present invention relates to an inverter, and more particularly to an energy-efficient low-voltage fluorescent lamp inverter. The technical scheme comprises an amplifying circuit, an oscillating circuit and a resonant circuit. The fluorescent lamp can directly use low-voltage direct current as a power supply, has the advantages of quick glow starting, high electric efficiency, namely power factor, power saving, energy saving and the like, and particularly can be directly used for lighting on vehicles and ships by using the storage battery as the power supply.
Description
The utility model relates to a kind of inverter, particularly a kind of energy-efficient low pressure fluorescent lamp inverter.
Existing low pressure fluorescent lamp inverter is though solved the use problem of fluorescent lamp on low-voltage dc power supply; But exist electrical efficiency is the low problem of power factor, thereby very power consumption.
It can be the fast energy-efficient low pressure fluorescent lamp inverter of power supply and starter with the low-voltage DC that the purpose of this utility model provides a kind of.
A kind of energy-efficient low pressure fluorescent lamp inverter comprises push-pull oscillator circuit, and its main points are: the output at push-pull oscillator circuit is in series with resonant circuit.Resonant circuit preferably adopts series resonant circuit.
Because the output at push-pull oscillator circuit is in series with resonant circuit, make circuit working in resonance condition, thereby the utility model can not only make fluorescent lamp directly make power supply with low-voltage DC, has also that starter is fast, electrical efficiency is advantages such as power factor height, power and energy saving; Particularly making fluorescent lamp can be power supply with the storage battery directly, is used for the illumination on the car and boat.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in detail:
Accompanying drawing is circuit theory diagrams of the present utility model.
Among the figure, produce the alternating voltage of required frequency after low-voltage DC is by amplification and oscillating circuit, the voltage of required frequency forms sizable electric current by resonant circuit again.When the build-up of luminance fluorescent lamp, because of capacitor C with the fluorescent lamp series connection
2Permanent in shunt capacitance C
1, make the total capacitance of resonant circuit approximate C
1, C
2Can be considered short circuit, again because of the characteristic impedance in the loop greater than the resistance Q in the loop doubly; Thereby, in capacitor C
1Two ends have just formed very high voltage, with the fluorescent lamp build-up of luminance.After fluorescent lamp is lighted, capacitor C
2Permanent in C
1, C
1Permanent again the resistance of capacitive reactance greater than fluorescent lamp, C then
1Can be considered open circuit; So circuit operating state at this moment is a resonance condition, the alternating voltage after the vibration all can be applied to lamp tube ends, thereby electrical efficiency is that power factor is very high.
In order to make electrical efficiency is that power factor is higher, has adopted the push-pull oscillator circuit that mainly is made of push-pull amplifier circuit and oscillating circuit among the figure, and amplifier transistor works on off state; Cause dried scratching for preventing that high-frequency current from intercoupling by the internal resistance of source and other circuit, among the figure, also the power input in push-pull oscillator circuit is parallel with by radio frequency choke L and capacitor C
3The filter of forming; For preventing that the both positive and negative polarity wrong from burning transistor, also be provided with protection diode D among the figure
