DC power is converted into AC power by the inversion process taking place in the inverter. This process of DC to AC Conversion is achieved by using a set of solid state devices like Insulated Gate Bipolar Transistors (IGBT’s.). These devices when connected in a typical H-Bridge arrangement oscillate the DC power thereby creating AC power.
An Inverter is an electronic device capable of transforming a DC (DC) current into an alternating current (AC) at a given voltage and frequency. For example, if we have to supply a household appliance that operates in alternating current 230V (50Hz frequency) but we do not have the AC power available, we can still power it by using an inverter such as a 12V (DC) . It is therefore indispensable
