| Abstract | ||
| : Multilevel inverter (MI) was known as an intelligent topology conversion form low to high voltage DC-AC Inversion. This paper introduces a form of hybrid multilevel inverter using proportion integer (PI) controller. This modifying technique employs the sine wave modulation inverted such the carrier waveform. Gate signals are activated by a PI controller, also, the “sinusoidal PWM control technique has been actuated in the circuit to provide an acceptable control level in the inverter output voltage”. The performance of the present technique has been simulated by the state of different charge. The integral control training simulator relative to the reflector unit step proposed amendment to the strategy is made by MATLAB / SIMULINK. | ||
