PWM control technology regulates the pulse signal''s width, and this circuit can alter the fundamental amplitude and form of the input voltage. This study will evaluate the three-phase inverter circuit''s operating principle, develop its control strategy, create a SIMULINK simulation model, and do a rough analysis using an LC filter.
Following points may be noted from the output waveform of three phase bridge inverter: Phase voltages have six steps per cycle. Line voltages have one positive pulse and one negative pulse each of 120° duration. The phase and line voltages are out of phase by 120°. The line voltages represent a balanced set of three phase alternating voltages.

PWM inverters can be broadly categorized into single-phase and three-phase types, each with distinct structures and applications. Single-phase PWM inverters consist of two main parts, the DC power source and the inverter bridge, typically use a full-bridge configuration consisting of four power switches, usually IGBTs and MOSFETs.
