摘要：
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 the dc-link boost voltage have been described in detail, which simplify the controller design and improve the transient response. The simulation and experimental results verified the validity of proposed control strategy.
