A Three Phase Inverter operates using six switching sequences to generate a stepped AC waveform. It is commonly used for induction motor drives, pumps, compressors, and basic industrial applications. Although the waveform contains more harmonics than sinusoidal PWM, it provides efficient torque and reliability for high-load equipment. Six-step inverters are cost-effective, easy to control, and ideal where precision waveform shaping is not critical, making them suitable for automation systems and legacy machinery.
