DC three-phase AC inverter

A three-phase inverter is a device that converts DC power into three-phase AC output. It typically consists of a six-step bridge inverter using a minimum of six thyristors to manage the conversion process1. The inverter operates by utilizing three arms, which are delayed through 120° angles to produce the required three-phase AC supply2. The conversion is achieved through a power semiconductor switching topology, where gate signals are applied at 60-degree intervals to create the necessary AC signal3. This model demonstrates a DC-AC converter. 3 leg Mosfet operated inverter is constructed . Can be used to demonstrate the relationship of input DC, output voltage, modulation index, filter selection and switching frequency. 3rd harmonic injection features
