This paper proposes an auto-tuning fuzzy PD controller to control the output voltage of a three-phase Z-source inverter (ZSI). The proposed scheme adjusts the proportional and differential coefficients (Kp and Kd) in real time in order to find the most suitable Kp and Kd for PD controller and to simplify the controller design. The proposed scheme is verified the validity by co-simulation in PSIM and...
This paper proposes a new constant control method of the output voltage of a voltage-fed three phase Z-source inverter (ZSI), in case of the capacitor voltage variations in Z-source network or the heavy changes of load. The modulation index for the reference output voltage of the ZSI can be calculated by the basic definition of the ZSI, the input DC voltage and capacitor voltage in Z-source network...
