How many switches are in a three phase inverter?
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

What is the difference between a single phase and a three phase inverter?
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.
