Voltage Inverter
- A voltage inverter is an electronic device that converts a certain DC input voltage into another AC output voltage.
- It receives direct current from a certain voltage and provides alternating current generally from a voltage different from the input.
How does it work?
- The voltage in the direct current is constant and the electric charge flows in only one direction.
- The magnitude and direction of the flow changes periodically with valleys and peaks that appears at regular intervals.
- The voltage inverter uses electronic circuits to make the flow of the direct current change direction periodically
- making it similar to alternating current.
- The inverter also uses a series of filters to make these changes of direction smooth and regular
- so that the resulting electrical energy can be used in most household electrical devices.
- These devices need the electricity they receive to have a specific voltage, continuous and well regulated.
- Alternating current is much easier to regulate and its voltage easier to change than direct current
- It is common to see inverters in electronic devices, such as PC power supplies
What are they used for?
- Most batteries, such as a car or a windmill and most renewable energy sources
- produce direct current while most electrical appliances work with alternating current.
- The main use of inverters is to transform the available continuous electric power.
- The alternating current that can be used for most electrical appliances.
- All can be used uninterrupted while the vehicle is running but it may not last more than half an hour with the engine of the vehicle stopped.
- You can also find inverters that connect directly to the battery through cables.
- It can be supplied to households through the general electrical network.
What capacity do they have?
- There are inverters with different output capacity, this capacity being measured in the total number of watts (or watts) they can supply.
- The capacity of a voltage inverter should be chosen by adding the total watts required by each of the devices that will be connected plus 50% more to be able to withstand possible consumption peaks.
- For example, if we are going to connect a DVD and a portable cooler, and each one needs 100 W, the inverter we use should have a minimum capacity of 300 W (100 + 100 = 200, 500 + 50% = 300).
- It is always convenient to acquire an investor with more capacity than we will need immediately so that we can connect more devices in the future without needing it without having to buy a new one.
What types are there?
- Most current voltage inverters can produce alternating current of square wave (modified sine wave) or pure sine wave.
- The square wave direct current does not have peaks and valleys as smooth as the alternating current that is in the electrical network of homes but it is valid that most electrical appliances work.
- Because they can be used and they are very cheap, the square wave inverters with the common ones.
