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.
The three-phase inverter consists of six switches, typically arranged in a bridge configuration, and each phase is connected to a load as shown in Figure 1. The switching patterns and timing of the switches determine the shape, magnitude, and frequency of the output voltage. 1. Three Phase 180° Mode Voltage Source Inverter
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
