Multi-level inverter (MLI) is become more popular emerging in recent years and very efficient power electronic device suited for medium high power utilities and industrial drives. Multi-level inverters are power semiconductor sources which are connected properly and controlled to generate a multi-step voltage waveform with variable and controllable frequency, phase and amplitude. This study deals with performance of a 5 level, 7 level, 9 level and 13 level inverter model. The harmonic analysis is examined for different levels with the different palm techniques. The harmonic analysis introduced to study the reduced total harmonic distortion (THD) level and depends on the gating of signals for different units an MLI. The various implement/analyze PWM techniques with different levels of multi-level inverter decreases switching loss and improves the output power and efficiency. It has been found that with increasing levels of multi-level inverter with less number of switches satisfies the required limits of harmonics. PWM control techniques is applied to the power pleesonic switches at appropriate conducting angles with regular intervals of delays. A recent / present technique called SHE (selective harmonic elimination) is also studied in order to decrease specific harmonics.
