This paper presents a direct peak dc-link boost voltage PID-like fuzzy controller in Z-source inverter. With this technique a constant peak dc-link voltage can be achieved with an excellent transient performance which enhances the rejection of disturbance, including the input voltage and load current variation, and solves the problem of the local dynamic output feedback stabilization of the serious...
This paper presents a high-performance Z-source inverter is proposed in this paper, which can overcome limitations of traditional Z-source inverter. The proposed Z-source inverter can operate at wide range load (even no-load) with small inductor, eliminate the possibility of the dc-link voltage drops, and simplify the inductor and controller design. The operation modes, voltage relationship of the...
This paper presents a PID controller for dc-link boost voltage in Z-source inverter. With this technique a constant capacitor voltage can be achieved with an excellent transient performance which enhances the rejection of disturbance, including the input voltage ripple and load current variation, and have good ride-through for voltage-sags. The shoot-through duty cycle modulation strategy for control...
A PID controller for direct peak dc-link boost voltage in Z-source inverter has been introduced. With this technique a high-performance inverter output voltage can be achieved with an excellent transient performance which enhances the rejection of disturbance, including the input voltage ripple and load current variation, and have good ride-through for voltage-sags. The peak dc-link voltage direct...
