An inverter converts the DC voltage to an AC voltage. In most cases, the input DC voltage is usually lower while the output AC is equal to the grid supply voltage of either 120 volts, or 240 Volts depending on the country.
The inverter may be built as standalone equipment for applications such as solar power, or to work as a backup power supply from batteries which are charged separately.
There are different types of inverters based on the shape of the switching waveform. These have varying circuit configurations, efficiencies, advantages and disadvantages
An inverter provides an AC voltage from dc power sources and is useful in powering electronics and electrical equipment rated at the AC mains voltage. In addition they are widely used in the switched mode power supplies inverting stages. The circuits are classified according the switching technology and switch type, the waveform, the frequency and output waveform.
Applications
Inverters are used for a variety of applications that range from small car adapters to household or office applications, and large grid systems. The major applications are but not limited to the following;
As standalone inverters
In solar power systems
As a building block of a switched mode power supply
