The role of the inverter, what is it for?
The inverter is an indispensable device for protecting equipment in the event of a power failure. It is important to know what is inverter and how to Inverter work, the different models available on the market and especially its various uses. Converter type continuous or alternating, an inverter is defined as an electronic device of power. It is capable of supplying alternating currents. Such an electronic device uses continuous electrical energy to operate. As such, its role may be considered contrary to that exercised by an apparatus such as the rectifier. In addition, it consists of a control interface, a charging circuit, filters and a storage battery.

what is inverter and how to Inverter work:
In this day we have to know what is inverter and how to inverter work properly, actually, Inverter is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. Also known in English as an uninterruptible power supply which is the French equivalent of the uninterruptible power supply, the inverter allows to protect many devices in case of power failure. This is the case, for example, for industrial devices, computer peripherals, and computers. This type of electronic device can be considered as an excellent way to protect devices against lightning, micro-cuts, voltage variations, electrical noise and power cuts.
The different types of inverter
There are two main types of inverters on the market: inverters and voltage inverters. However, this type of power device can be autonomous or not. Indeed, a non-autonomous inverter corresponds to a rectifier assembly all thyristors also called Great Bridge. Such an assembly operates as a natural switching inverter. To do this, the connection network of this system must assist its natural switching. With regard to the autonomous inverter, it makes it possible to obtain a voltage with a certain radio frequency. The operator can adjust this frequency, which can also be fixed. This type of inverter does not use the electrical network for its operation.
In addition, in the field of the inverter, several technologies are used. These include On-line technology, Line Interactive technology, and Off-Line technology. Models using Line Interactive technology are characterized by their ability to readjust the voltage in case of decline. Do not use its own resource to adjust the voltage drop, this type of UPS can cope with a lack of power or excess voltage. As for the inverter using online technology, it allows regulation and filtering of electricity. With such a device in permanent charge, there are no micro cuts or change of voltage, that’s why this model is best suited for organizations and businesses protecting their electrical equipment. In the case of the Off-Line model, the system failure is supplemented by an accumulator thus ensuring the protection of devices such as PCs that operate using switching power supply.
The various uses of the inverter:
The uses of an inverter are numerous. Indeed, this device is indispensable in several areas. This is particularly the case for variable speed drives for alternative machines, for nomadic consumer TV reception, for switched-mode voltage converters or DC voltage converters, for arc welding and for devices operating with a frequency specific. In the category of devices having a specific frequency where the inverter is used, mention may be made of electricity or ultrasound generators, feeding of cathode lamps, feeding of fluorescent lamps, uninterruptible power supplies, and emergency power supplies.
With regard to variable speed drives of alternative machines, the use of an inverter allows the use of a voltage having a frequency that can be adjusted. In the field of arc welding, this type of electronic power arrangement is used to deliver a single-phase alternating current with a frequency between 5 and 20 kHz. This gives the possibility to use current transformers. Such machines are lighter and smaller than those using a frequency between 50 and 60 kHz.
The criteria for choosing an inverter:
we already learn what is inverter and how to Inverter work, so If you wish to use an inverter optimally, you must make your choice taking into account certain criteria. Indeed, when buying this type of electronic power device, it must focus on its functionality, power, and level of autonomy or performance. Speaking of autonomy, it is a question of considering elements such as performance and recharge time, which must have an average duration of between 5 and 6 minutes.
As for the power, it must be chosen according to the devices that must be supplied. Thus, if it is to supply a 90 W element, it is necessary to opt for an inverter of at least 150A. At the functional level, it is necessary to choose an inverter offering functions such as noise filtering or mitigation of distortions. In general, the user must choose his inverter taking into account his needs.
