Where it is not practicable to gate the AC supply from the main and power backup, inverters are frequently required. To convert DC power to AC power, an inverter circuit is utilized. There are two types of inverters: quasi-or modified inverters and true/pure sine wave inverters. Modified or quasi-inverters are less expensive than these True/pure sine wave inverters. These altered inverters generate a sine wave, which is utilized to supply power to sensitive electronic devices. Here, a straightforward voltage-driven inverter circuit is constructed using power IGBT switching devices. With the aid of a step-up transformer, the circuit converts a 12V DC signal to a single phase 220V AC. The fundamental idea of any inverter circuit is to apply oscillations across the transformer primary by amplifying the current and creating oscillations with the supplied DC. Depending on how many turns the primary and secondary coils have, this primary voltage is then increased to a greater voltage.
