Abstract
The invention provides an electronic ballast which is applied to 220V alternating current and low-voltage direct current so as to switch on fluorescent lamps. According to the electronic ballast, a direct current inversion booster is additionally adopted; high-frequency and high-voltage alternating current is subjected to high-frequency rectification, so that positive and negative high-voltage direct current can be formed, and is connected with the positive and negative electricity which is converted from 220V alternating current through rectification, so as to be adopted as the power source of the ballast to switch on the fluorescent lamps.
Description
Electric ballast does the high-voltage DC power supply needed for switching tube, is then gone to light fluorescent tube by electric ballast, and the high-frequency and high-voltage alternating current that this DC inversion stepup transformer exports comes commutation technique field with four high-frequency rectification diodes
Electronic ballast for fluorescent lamp
Background technology
The use of fluorescent lamp has had for a long time, from use Inductive ballast to use electric ballast until also have today a lot of people still making fluorescent tube fluorescent lamp, although there has been the appearance of high-efficiency energy-saving LED fluorescent lamp, but because manufacturing problem of improving quality and the high difference of cost, select fluorescent tube fluorescent lamp to be at present the people of throwing light on also a lot, because its light is beautiful, cheap or generally welcomed by the people.
But the use along with the newborn energy-solar cell or the landlord in AC-less power also have use people when having a power failure always to wish to use direct current to throw light on to light fluorescent tube, can not have at present can be dual-purpose fluorescent lamp ballast, I sees this vacancy and has invented the electric ballast that can be able to use at alternating current 220V and direct current, manufactures the choice for use that the dual-purpose electronic ballast produced more is conducive to demander like this.
Summary of the invention
DC-AC two-use electronic ballast for fluorescent lamp, its feature: on the circuit of existing electric ballast, add the high-frequency and high-voltage alternating current boosted by DC inversion, after rectification, enter out high voltage direct current receives in the positive and negative electric position of direct current of 220V AC rectification output, the positive terminal gone out in 220V AC rectification is connected a high-frequency diode, high-frequency diode input termination power positive electricity output, high frequency animals and plants output just and inversion boosting and the positive electricity parallel connection of hf rectifier that comes, the former negative electricity of 220V AC rectification and the negative electricity of high-frequency rectification are in parallel, light remaining of fluorescent tube and use primary electron ballast.
Like this in time being used in the alternating current of 220V city voltage operation principle be by before conventional electronic ballast carry out work, circuit does not almost change, positive electricity only after rectification exports a high-frequency diode of having connected more, but this diode does not have influence on its work.In time being used in DC power supply, galvanic positive negative electricity is connected on the positive and negative wiring position of inverter, at this moment inverter work, it becomes high-frequency and high-voltage alternating current the DC power supply inversion boosting of low-voltage, and the alternating current of this high-frequency and high-voltage have passed through the rectifier that is made up of high-frequency diode and just can go to light fluorescent lamp work by primary electron ballast and do illumination it becomes high voltage direct current and used.
Accompanying drawing explanation
Accompanying drawing 1 is the wiring schematic block diagram of DC-AC two-use electronic ballast.
Fig. 2 is the positive negative electricity figure in parallel mutually that two rectifiers export.
Embodiment
This dual-purpose ballast is very simple, if main circuit adds that a high-frequency high-voltage being boosted out by low-voltage direct inversion boosting device is in parallel just passable through directly being gone by high-frequency diode rectification high voltage direct current out with former 220V AC rectification positive negative electricity out, method in parallel is connected after a high-frequency diode and just just connecing with inversion boosting rectification direct current out in the positive electricity place exported in former 220V AC rectification, negative connect negative.
This above DC inversion stepup transformer also need to export there is certain power high-frequency high-voltage, the generally general power also having tens watts.High-frequency diode needs reverse breakdown voltage also should at more than 400V, after having loaded onto adapter, ballast is also by being originally equally contained on daylight lamp bracket, but note handing over the input of straight power supply to separate separately, the good interchange of mark, direct current, just not confused so in use, direct current input can not access 220V AC power.
