What is a throttle and what is it for? Throttle is a German word that means smoothing. Specifically, we will talk about the electric throttle. Nowadays it is difficult to find an electrical circuit that does not contain this device, which is widely used in technology even in the digital age. It is needed for regulation or cutting, depending on the purpose - to smooth out sharp current surges or cut off electrical signals of a different frequency, to separate direct current from alternating current.

Design and operating principle

First of all, let's talk about what this circuit element consists of and how it works. In the diagrams the throttle designation is as follows:

The appearance of the product may be as in the photo:

This is a coil of wire wound around a core with a magnetic core, or without a housing in the case of high frequencies. Similar to a transformer with only one winding. A short excursion into physics, the current in the coil cannot change instantly. Let's conduct a thought experiment - we have an alternating current source, an oscilloscope, an inductor.

During the onset of the half wave, we observe an increase in current with a delay, this is caused by the induction of magnetic flux in the core. There is a gradual increase in current in the windings, when the signal from the alternating current source goes into decline, we observe a decrease in the current in the inductor, again with some delay, since the magnetic field in the magnetic circuit continues to push the current in the coil and cannot quickly change its direction. It turns out that at some point the current from an external source counteracts the current induced by the magnetic circuit of the inductor. In AC circuits, the purpose of the inductor is to act as a limiter or inductive reactance.

For direct current, this circuit element is not a resistance or a regulating element. This effect is used for devices in electrical circuits where it is necessary to limit the current to the required value, while avoiding unnecessary bulk and heat generation.

You can also watch an interesting explanation on this issue in the video:

A visual comparison explaining how it works

Theoretical part of the question

Scope of application

Throttle is designed to make our lives brighter. Specifically in fluorescent lamps, it limits the current through the bulb to the desired value, avoiding its excessive increase through the lamp.

The fluorescent lamp is mainly composed of choke, starter, fluorescent lamp. In a nutshell, the description of how a fluorescent lamp works is as follows:

From the network, the current passes through the inductor to one of the filaments of the fluorescent lamp, then it goes to the starter device, then to the second filament and goes into the network. In the starter device, a bimetal plate is heated by a glow discharge of gas, straightens under the influence of heat and closes the circuit. At this moment, the filaments at the ends of the light bulb begin to work, heating the mercury vapor in the bulb of the fluorescent lamp. After a short period of time, the plate in the starter cools down and returns to its original position. When the circuit breaks, there is a sharp surge in voltage in the inductor, gas breakdown occurs in the bulb of the fluorescent lamp, and a glow discharge occurs, the lamp begins to shine, the working lamp shunts the starter, turning it off from the circuit with a lower resistance.

The electronic circuits of modern economic fluorescent lamps also contain the element discussed in the article, but due to higher frequencies it has miniature dimensions. But the operating principle and purpose remain the same.

Also, the choke is a mandatory element in the circuits of DRL lamps and CDM metal halide lamps.

In switching power supplies in converter circuits, the purpose of the inductor is to block sharp surges from the transformer, passing a smoothed voltage. Roughly speaking, in this case it plays the role of a filter.

They are also installed in electrical networks, but are called reactors. The purpose of the arc suppression reactor is to prevent the occurrence of an independent arc during a single-phase short circuit to ground, as well as other reactors that somehow regulate or limit the amount of current through them, specifically or in case of an emergency.

Using a choke, you can improve a cheap one or by installing it in the secondary circuit. A welding transformer assembled with a choke will weld no worse than branded devices, the arc will become smooth and will not break, the seam will be evenly filled.

Ignition of the arc will become much easier and the mains voltage drop will have less effect on the appearance and burning of the arc. Even a non-specialist can quickly achieve good results in welding by making all kinds of crafts at home.

Where is the product used?

So we looked at the design of the throttle, its operating principle and purpose. We hope that you now fully understand why this element of the circuit is needed!
