Modern electronic systems cannot function without three-phase inverters, which transform DC power into three-phase AC power with adjustable amplitude, frequency, and phase difference. They are essential in several applications, including as power distribution networks, renewable energy systems, and industrial motor drives.
Overview: Single Phase vs. Three Phase For a given power requirement, a three-phase converter requires less current, is a smaller size, and produces less power ripple than a single-phase converter. For example, an 11-kW single-phase PFC requires 48 A, while an 11-kW three-phase PFC requires only 16 A per phase.
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
Another issue of the three-phase inverter is the common-mode voltage (CMV), which is excited by the switching behavior of the power semiconductor devices .
