Use two half-bridge circuits to make a full H-bridge. A less common inverter circuit used in induction heating is the quarter-bridge or single-switch inverter. Introduction. Two commonly used configurations of an output inverter are discussed in the following sections. Full bridge inverter circuits also known as the H-bridge inverter, are the really economical types as these never rely on a center tapped transformers yet still have the ability to work with the proposed push-pull abilities right across the whole primary winding of the connected tansformers. Meaning, If the top switch is closed (ON), the bottom must be OFF, and vice-versa. The H-bridge inverter has two functions, it has to synthesis the inversion voltage of the dc link voltage plus generating the zero state voltage (OV) at the output voltage (Vab) by connecting the upper two switches (Ql, Q3) or the lower switches.

Inverters frequently employ the use of transformers, capacitors and inductors to filter the PWM waveform and reduce the harmonic content. A full bridge inverter is also referred to as an H-bridge inverter circuit usually requires a relatively complex circuitry for accomplishing its working conditions.
