Can anyone tell me which of the electronic components have switching properties?

The theme of switching components is the working principle of transistors, including IPM, IGBT, and thyristor. Of course you can also use relays, hehe.

IGBT and IPM can replace the thyristor, the main disadvantage of the thyristor is that the voltage drop is too large, and the collector joint has less anti-bias charge, so it shows a relatively large resistance.

If the best alternative to the thyristor is, of course, IPM, it is the best switch in the control circuit, with high stability, high safety, small voltage drop, high withstand voltage, etcIt's just that the only drawback is that the ** is too high, is the reason for the monopoly of technology, the world seems to be able to do high-quality IPM in Japan, Germany, and the United States, I was in the original company was to do control circuits, we used 800 amperes of Japanese Sanling IPM, a piece of two thousand three.

IGBT can also be replaced, ** cheaper, but he is not like IPM He has no protection circuit, and the maximum specification of IGBT can not run much current, if you want to run a small current, you can choose IGBT, large current will need parallel control, need a little technical PR.

There are many diodes with switching properties, but it is said that they can work in that state. Thyristor is thyristor, you can use relays without thyristors, and it is not bad to design your own circuit.

MOSFET or triode combination (such as 555 time-based circuit, etc., a single triode or MOSFET leakage is large, and there is a range in the amplification area that is neither on nor off).

1. Thyristor, which can be used as DC switch and AC switch, thyristor is divided into one-way and two-way, and also derives fast thyristor, which can turn off thyristor, reverse conductive thyristor, optical control thyristor, etc.

2. Power Transistor (GTR).

3. The gate can turn off the thyristor (GTO).

4. Power MOSFET.

5. Insulated Mountain Bipolar Transistor (IGBT) In addition, there are more commonly used non-contact switching solid state relays That's all I know, and if you want to know more, please check it online.

An electronic component is a basic element in an electronic circuit, usually in a separate package, with two or more leads or metal contacts. Electronic components must be connected to each other to form an electronic circuit with a specific function.

For example, amplifiers, radio receivers, oscillators, etc., one of the most common ways to connect electronic components is to solder to a printed circuit board. Electronic components may be individual packages (resistors, capacitors, inductors, transistors, diodes, etc.) or groups of varying complexity, such as:

Integrated circuits (op amps, reactors, logic gates, etc.).

Busbars, disconnectors, circuit breakers, current transformers, voltmeters, ammeters, cabinets, etc. Low-voltage switchgear is suitable for power plants, petroleum, chemical, metallurgy, textiles, high-rise buildings and other industries as power transmission, distribution and power conversion. The product conforms to the standard of low-voltage switchgear (IDT IEC60439-1 1999).

The low-voltage switchgear is a product listed in the "Catalogue" of 3C certification compulsory certification products.

Diodes, transistors, thyristors, etc.

<> the commonly used switching components in digital circuits are mainly known as follows:

1. Triode, the full name should be semiconductor transistor, also known as bipolar transistor, transistor, is a semiconductor device that controls the current, and its function is to amplify the weak signal into an electrical signal with a large amplitude value, and is also used as a contactless switch. Crystal transistor is one of the basic components of semiconductors, which has the effect of current amplification and is the core component of electronic circuits;

2. Lu Sui diode, a device with two electrodes, only allows the current to flow in a single direction, and many of the use deficit sections are applied to its rectification function. Varactor diodes, on the other hand, are used as electronic tunable capacitors. The most common function of diodes is to allow only current to pass through a single direction, so they can be used as switching elements;

There are many switching elements, mechanical switches, electronic switches. Broadly speaking: as long as the components that can turn the circuit on and off are.

Mechanical silver switches are well understood, and there are many types of electronic switches, such as transistors, diodes, thyristors, tubes, electromagnetic switches, electric switches, magnetic switches, reed switches, proximity switches, light control switches, vacuum switches, mercury switches, inflatable, oil-filled switches (such as sulfur hexafluoride, oil switches...).Ascension Feast....）…There are too many to list.

1. Among the following early hand components of Fuxin, the switching electrical appliances are.

a.Combination switches.

b.Contactors.

c.Travel switch.

d.Time relay land hall suspect.

Correct Answer: a

The commonly used electric destruction chain sub-elements in circuits are called ().

a.Capacitance. b.Inductance.

c.Electrical fiber noise.

d.Transistor.

Correct Answer: Capacitor; Inductance. Resistance; Transistor.

The X0D X0AU6 is a photocoupler, commonly used such as PC817. Because the primary and secondary of the switching power supply need to be isolated, there can be no direct circuit connection between them, so the secondary voltage signal is turned into an optical signal with it, and then it becomes an electrical signal inside it to complete the feedback and voltage stabilization process, and at the same time achieve isolation.
