Design of 7-level hybrid inverter control circuit

Abstract EN

Use of multilevel ‘inverters is becoming popular in the recent years for high power applications.

The important feature of these inverters is of having low harmonics content in (lie output voltage.

The switching angles in a multilevel inverter are computed so as to produce an ae output voltage with minimum harmonics.

A new control circuit is designed to achieve these angles.

Hi is control circuit has the ability to control the RJMS output voltage using sinusoidal pulse width modulation ( SP\VM ).

The results presented in this work prove the ability of the designed control circuit to gain the required at output voltage with minimum distortion.
