The basic three phase bridge inverter is a six-step inverter. A step is defined as a change in the firing sequence. A 3-phase thyristor bridge-inverter is shown in Fig. 11.49. Th 1 to Th 6 are the six load-carrying thyristors while D 1 to D 6 are the free-wheeling diodes.
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
