How yes si we will direct the protection from the energy-saving lamp

Compact fluorescent lamps (CFL or "Chesting for Energy") have appeared in daily life for a long time, but they still hold either a primacy of lighting devices, or a water shield of a place. Those sa are compact, economical and can work and work instead of an ordinary mug with a litter box. But these devices are imat and lacking. Contrary to the manufacturer's declaration of an exploitative stomach, the CFL will often fail, without dori and sa they have exhausted the C resource.

Tova nai-chesto, lie on the unstable voltage and most of the "shrakane" on the switch. Is it possible that, for some reason, the device burned out, for some reason, the device was enough to bet? Siguren! In the basin, there is more information and we will save you from the energy-saving lamp with your own mother.

Device and principle for operation on electronic ballast

First, let's remember and work on the electronic ballast for compact fluorescent lamps, we will somehow recognize the device and how it works. The main task for the ballast:

• start the gas-discharge tube on the lamp;
• maintain current and voltage, necessary for work on the trbat.

Somehow I can see the classic circuit for an electronic ballast or, as you rightly call it, an electronic ballast (Electronic control device on a starter).

Electronic ballast circuit (electronic ballast) for energy efficient lamps

Vsshchnost is normally impulsively stored from a small difference, but more often than not. The intervoltage of the se supply to the bridge of the current converter VD1-VD4, removing it from the capacitor C1 and se supplying the km of a high-frequency (frequency on its own treptene 10-60 kHz) generator, is sgloben on transistors VT2, VT3. It is generated in it all thanks to the positive feedback, some of it is powered by the transformer T1, which starts when it is applied to the power, it should be on the symmetrical dinistor DB1.

Impulse voltage prez current-limiting inductors T2 se supplying a energizing lamp, directed under the format to the winding pipe. Capacitor C8 e is needed for high-voltage impulses, which are necessary. Vednaga trace kato in the lampata, damage to the gas section, using the throttles, somehow limiting the current to the nivoto, it is necessary to work on the lampata. Thy kato chestotata for tension is relative to the temple, the throttle is a lot compact.

Important! Manufacturers of high-energy lamps use different ballast circuits in their products, but the principle of operation is the same.

Differences in design on lampata from impulse block

What is the difference between a CFL electronic ballast and a surge protector (UPS)? At the first place, at the exit to the ballast, a current-limiting choke was installed. Osventova verigata nyama galvanic isolation for intervoltage from the outlet, therefore, all the elements of the verigata, some of which are protected from electronic ballast, but under the stomach, the voltage is frightening. Now we have some experience and let’s direct it to protect the lamp from the energy-saving lamp.

In addition to these differences, the electronic ballast is subjected to an impulse voltage, which is stored normally and constantly.

Scheme for the change on electronic ballast in UPS

For yes, convert the electronic ballast in storage, and it is necessary to solve three problems:

1. Osigurete electrical safety, which provide galvanic isolation.
2. Namalete the initial voltage on the converter, then it is high enough for the output of the si - from the order of 100-150 V.
3. Correct the initial voltage.

Ako imate the need to protect the unit from a low power - up to 15 W, then this is not a special equipment for electronic ballast. Desetina centimeter winding of bodies, four diodes and a chief capacitor are sufficient. And, taking it apart, you need an electronic ballast from a 40 W lamp. Some and see the modified scheme:

Simply 12 V switching protection from electronic ballast to fluorescent lamp

Here, the throttle plays a role in isolation and in a short time stepping down the transformer to store it, and the current rectifier (diode VD8-VD11) is not directed from constant voltage from pulsed voltage. Capacitor C8 and C9 will erase it. In the opposite case, work on the protection of the block is not distinguishable from the schematic for the electronic ballast.

We will also send the conversion to the electronic ballast into the stored network in the next sequence:

1. Remove the fluorescent tube and capacitor C8.
2. In between, conduct the conductor on capacitor C6, C7 and throttle T2, which is the first to leave the lamp. Nay-lesniyat start and send the goods, just yes, send the connection to the cables to the lampata.

Now nashiyat drosel e natovarvaneto on the converter. Leaving itself and all navie secondary winding on top of it.Thy kato chastotata on the conversion and delivery is high, but it is necessary to wind it up a little with a winding with a diameter of 0.5-0.8 mm. The difference between the sartsevinata and the winding on the throttle is small, but it’s not enough for a bit of a winch, which I chose experimentally.

The technique on the winding is traceable. Navivame about 10 turns of the cato is secondary, connect a diode bridge with an anti-condenser to it and protect it with a resistor with a power of about 30 W and a resistance of 5-6 ohms. Measure the voltage across the resistor with a constant voltmeter. Next to separating the received stress on the broya on the curl and the stress received from a single curl, izliza. Now we need a voltage (12-13 V) for the last winding and we need a winding for the secondary winding.

Yes, let's suppose that after the catho nawihme is 10 turns, we get the voltage from 8 V. 8/10 = 0.8. Tova means, che unitedly produced 0.8 volts. We need it from 12. Divide 12 by 0.8, get 15. And so, tryabva and naviem 15 twisting.

Standard and modified protection of throttle from electronic ballast

In a diode bridge, you can use any kind of corrective diode for back voltage from as little as 25 V and current from 1A. It’s better to use the diodes on Schottky for these purposes - they have a lower voltage drop and work better in the impulse mode, they are more efficient for safekeeping. Instead of C8, a ceramic capacitor with a capacitance of 0.1 μF can work, C9 - an electrolytic capacitor with a capacitance of 10-50 μF and a working voltage of at least 25 V.

Everything in the garden is satisfied from the verigata on such a zahranvane, but in spite of the negativity, the exit is not a stabilizer. I mean, it’s hard to oscillate from promyanat to mrezhata.The situation is easy to get rid of from the Tazi, by installing a 12-volt stabilizer in the chain. The graden stabilizer KR142EN8B or the strange analog L1812 bi-beat is ideal for the tazi intact. In this case, the fragment on the verigata is also taken out as follows:

Protecting the chain ss stabilized the initial voltage

Capacitor C10 and C11 and take it with you, take the ratings of C8, C9.

How to increase power

The usual power on the CFL is comparatively low and varied from 10 to 40 watts. It’s not good for theory, but for practice, the work is falling apart from current-limiting chokes. That does not allow for self-produced protection and development of maximum power, firstly, for the sake of its current-limiting properties, and secondly, for the sake of its own low power. With an increase in the current of the magnetic wire, the ground and work in the saturation mode, paint the efficiency on the storage and pre-commissioning, turn on the transistors, and the pre-production is in vain.

How can you send relatively powerful protection from energy-saving lamp? The task is not sensible and difficult, sharply scrutinized on the right. For yes, send the goods, it is enough to replace the choke with a relatively powerful impulse transformer. Understand this, comrade, the research for the task of knowledge in the field of radio engineering, but deserve it.

The transformer can be taken, for example, from unnecessary protection from a computer or other office equipment (printer, scanner, small TV, etc.). You also need a resistor with a power of 3 W and a resistance of 5 Ohm, as well as a new capacitor for high voltage with a nominal value of 100 μF and a working voltage of at least 350 V.

Protecting the chain with increased initial power

Here, instead of the inductors of the semontir, the transformer is pulsed, and the primary winding is the basin, which was connected to the converter (high voltage), and the secondary is lowered. In addition, the resistor R1 is selected with a higher power, and the capacitance for the smoothing capacitor C1 (after modifying the circuit C0) is increased to 100 μF. On the contrary, the case of verigata has practically not been changed, but now it is capable of delivering current from 5-8 A to goods at a voltage of 12 V. Such storage can still be used with a screwdriver and similar 12-volt tools.

And finally, not a little preporka

1. With the first starter, it’s good and you’ll modify the modified one to save the km through a lamp with a 220 V 60-100 W light switch. Ako ima sinka vv verigata, togava lampata shche burn brightly enough. Comrade, save the transistor from damage in case of sins during installation.
2. Before starting, the block is protected for a long time; In this case, the transformer and transistor are not shaking and they heat up over 60 degrees Celsius.
3. There is a lot of heat on the transformer, more trembling and winding up a gradual winding from a debel conductor.
4. Ako transistors are a lot of grief, those are shaking and equipping with small radiators.
5. Do not tryabva and use such a zahranvane for zarezhdane and zahranvane on skypi jadzhi. Much safer, yes, buy factory-preserved. Tova sche struva is a lot of things from repairs, for example, to a laptop or a smartphone.

Maybe you can talk about converting it to electronic ballasts for compact fluorescent lamps in pulsed storage.Ako ste read the article carefully and imate a little bit of disassembly for radio engineering, then you can do it yourself and do it with the tazi is a simple revision.
