A 3 phase inverter circuit diagram converts DC voltage into balanced three-phase AC supply using six switching devices. What is a Three Phase Inverter? A three phase inverter is an electronic power conversion device that transforms DC input voltage into a balanced three-phase AC output.
The voltage source inverter (VSI) is a commonly used power inverter. It converts a DC voltage into a three-phase AC voltage. So a three-phase inverter is required.
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
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.
