What is an Inverter Inverter and how does it work?

Inverter Inverter is a device that helps to switch electricity from direct current. is alternating current, enabling AC devices or electrical appliances to be used with direct current, such as motors, fans, air conditioners, etc.

operation of the inverter

in that inverter system There are three internal structures:

  • Converter Circuit : Converts alternating power from AC. power supply (50 Hz) to direct power (DC Voltage).
  • Inverter Circuit : converts direct voltage (DC Voltage) into alternating voltage (AC Voltage) that can change voltage and frequency.
  • Control Circuit: Controls the operation of the converter. and inverter set

The working principle of the inverter starts from The converter circuit converts AC power from a conventional power source with constant voltage and frequency. into direct current After that, the inverter circuit converts the electricity from direct current to alternating current. that can adjust the pressure and frequency The control circuit acts to control the operation of the converter circuit. And the inverter band to suit the properties of 3-phase Induction motor, commonly used in electrical equipment that uses backup power. To solve the problem of overload, undervoltage, outage and interference. to prevent damage to electrical equipment

How many types of inverters are there?

Grid-Tied Gritty Inverters

receive direct current power produced from solar panels or direct current from the battery then converted to AC power and supplied to AC appliances and helps maintain a stable voltage level

Micro Grid Inverter

It has a similar function to the Grid-Tied type, but differs in that it can convert 1 power per 1 solar panel. This can help reduce the use of AC power cables.

Micro Grid Inverter

Able to supply power like home power Including electrical appliances with induction motors as components such as motors, water pumps, refrigerators, but the disadvantage is the high price.

Modified Sine Wave Inverter

Not applicable to all types of electrical appliances. But the advantage is that it's cheap. making it widely used But now this type of inverter has been developed for higher efficiency. can be used with a variety of electrical appliances Including electrical appliances that have brushed motors as components such as fans, drills, grinders, etc.

How to buy an inverter

choose inverter To suit the job: choose to buy more than the Watt of electrical equipment. By adding together the total number of watts of electrical equipment, such as a 10-watt bulb and a 70-watt washing machine (10 watts + 70 watts = 80 watts), therefore, an inverter of more than 80 watts must be selected. motor load There must be enough allowance for the size of the inverter as well. to prevent electrical surges at the beginning

choose inverter From a trusted brand: There are many inverters in the market. But sometimes inverters that are too cheap may not be of quality and standards, resulting in problems during use. So should choose from the most trusted brands.
