A Six Level Diode Clamped Multi Level Inverter with APOD PWM

In this paper a six level diode clamped multi level inverter (DCMLI) with alternate phase opposition disposition (APOD) PWM technique is discussed and simulated using Matlab/Simulink. This DCMLI is capable of giving an output of six levels without a zero level. The six level consist of equal positive and negative level. The inverter uses five carrier waves, and one trapezoidal wave as the reference signal for pulse generation. The THD analysis for the same is carried out.
