General introduction to an Inverter
An inverter is used to produce an un-interrupted 220V AC or 110V AC (depending on the line voltage of the particular country) supply to the device connected as the load at the output socket. In general it converts DC to AC,which allows you to run electrical equipment off your car or marine battery for mobile applications, emergencies or simple convenience.
Power inverters produce one of three different types of wave output:
- Square Wave
- Modified Square Wave (Modified Sine Wave)
- Pure Sine Wave (True Sine Wave)
The three different wave signals represent three different qualities of power output and consequently, three different price categories. Square wave inverters result in uneven power delivery that is not efficient for running most devices. Square wave inverters were the first types of inverters made and are obsolete.Pure sine wave inverters are the most expensive, but they also deliver the most consistent wave output.
General applications of an Inverter:
- DC power source utilization
- Uninterruptible power supplies
- HVDC power transmission
- Variable-frequency drives
- Electric vehicle drives
Different types of inverter circuit are available in the web like 100 watt inverter circuits and various other power ratings. 100 watt type is little applicable in commercial needs, but it can be used for study purposes.
