A three phase bridge inverter is a device which converts DC power input into three phase AC output. Like single phase inverter, it draws DC supply from a battery or more commonly from a rectifier. A basic three phase inverter is a six step bridge inverter. It uses a minimum of 6 thyristors.
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.
In particular, considering “full-bridge” structures, half of the devices become redundant, and we can realize a 3-phase bridge inverter using only six switches (three half-bridge legs). The 3-phase bridge comprises 3 half-bridge legs (one for each phase; a, b, c).
Commonly the full-bridge topology is used for three-phase inverters. For three-phase applications including motor drives, UPSs, and grid-tied solar inverters, the three-phase full-bridge inverter topology is a frequently used design. The architecture is Figure 19: The Topology of a Three-Phase Full Bridge Inverter
