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.
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
These include topologies for single-phase such as two-level H-Bridge with bipolar modulation, three-level H-bridge with unipolar modulation, HERIC and totem-pole (TIDA-010933 which is a 1.6kW rated for inverter stage). TIDA-010938 depicts an inverter stage rated up to 4.6kW and can be configured into unipolar, bipolar and HERIC based converters.
Three-phase topologies distribute current across three legs rather than two, reducing RMS current per switch by √3 for the same output power: versus single-phase: The reduced current stress allows three-phase inverters to achieve higher efficiency (typically 97-99%) compared to single-phase (94-97%) at power levels above 5kW.
