Full bridge inverter is a topology of H-bridge inverter used for converting DC power into AC power. The components required for conversion are two times more than that used in single phase Half bridge inverters. The circuit of a full bridge inverter consists of 4 diodes and 4 controlled switches as shown below.
It is a common topology in power electronics conversion. The full bridge inverter consists of four switches (S1, S2, S3, S4) that work in pairs to control the direction of current flow, thereby generating an AC voltage. The typical operation is as follows:
Half bridge inverter: Simpler circuit design with only two switches to control, making it easier to implement and control. It is effective for medium to low power applications. Full bridge inverter: Higher cost due to more switches and complex control logic.
The controlled switches for Full-bridge inverters can be BJT, IJBT, MOSFET or thyristors. Controlled switches considered in this article are thyristors. The general concept of a full bridge inverter is to alternate the polarity of voltage across the load by operating two switches at a time.
