What is Inverter?
2023-02-10
Nowadays, our society cannot live without various kinds of power supply, which makes our life colorful. These electronic products are also inseparable from the inverter, so what is the inverter?
Inverter is a kind of power adjustment device composed of semiconductor devices. It is mainly used to convert DC power into AC power. It is composed of a booster circuit and an inverter bridge circuit. The booster circuit steps up the DC voltage from the solar cell to the DC voltage required for inverter output control. The inverter bridge circuit converts the boosted DC voltage equivalently to the AC voltage of the common frequency. The inverter consists mainly of switching elements such as transistors. By repeatedly switching the switching elements on and off in a regular manner, the output is changed from DC to AC.
Of course, such an inverter output waveform generated simply by the on and off circuit is not practical. Generally, high-frequency pulse-width modulation is required to narrow the width of the voltage near the ends of the sine wave. The width of the voltage in the center of the sine wave widens and always allows the switching element to move in one direction at a certain frequency during the half cycle. This creates a pulse train. The pulse wave is then allowed to pass through a simple filter to form a sine wave. The inverter not only has the function of DC-AC conversion, but also has the function of maximizing the performance of solar cells and the function of system fault protection.
Simply to say, an inverter is an electronic device that converts low-voltage (12 or 24 or 48 volts) DC power into 220 volts AC power. This is because it is rectifying 220 volts AC into DC to be used. The inverter is the opposite of this, hence the name. In an era of "mobile", mobile office, mobile communication, mobile leisure and entertainment. In a mobile state, not only do you need low-voltage DC power supplied by batteries or electric batteries, but you also need 220-volt AC power, which is indispensable in everyday environments. The inverter can meet the demand.
First, features of the inverter.
The first point is that the inverter has a fast start and a very high efficiency of conversion. It is well worth mentioning that after the improvement, all aspects of its performance and functions have been very much improved. The speed of converting the current has been increased a lot,
1.which makes its overall working efficiency also improved to a great extent. Therefore, people don't need to worry about the speed of its conversion.
2.The second point is that the safety of the inverter is excellent. The safety of electricity is crucial. When developing the inverter, the developers have taken into account the short circuit, negative pressure, and over temperature to solve these problems. Therefore, it is a very safe power tool, and there is no need to worry about safety hazards in the process of using it.
3.The third point is that the inverter also has very good stability. In the event of insufficient voltage, or negative voltage, etc., it can better maintain its performance will not change.
4.Good physical properties: the product uses a full aluminum shell, good heat dissipation, hard oxidation treatment of the surface, good friction resistance, and can resist a certain external force of extrusion or banging.
Second, scope of use.
1.Office equipment: fax machines, notebook computers, cell phones, printers and monitors
2.Home appliances: TV sets, VCRs, game consoles, stereos, VCDs, DVDs and refrigerators, etc.
3.Outdoor travel: field lighting, microwave ovens, cooking, etc.
4.Outdoor work: power tools, vehicles for assistance, rescue and relief, business promotion, etc.
5.Leisure and entertainment: cell phones, PDA, digital cameras, digital video cameras, battery charging, GPS satellite navigation, etc.
Inverters have a wide range of applications and can be used in various types of vehicles, such as cars, ships and aircraft. With the development of technology, users need to use more and more electronic devices on the move, inverters can provide sufficient AC power for these devices at any time to provide a better solution for users.
