This paper presents a new adjustable-speed drives (ASD) system which based on the high-performance Z-source inverter (named high-performance Z-source inverter ASD system). It can overcome limitations of original Z-source inverter ASD system. The proposed Z-source inverter ASD system can operate at wide range load (even no-load) with small inductor which is very suitable for ASD system, eliminate 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...
