Control Algorithms for CSI in Direct-Drive Wind Power Generation System;

Then the working method of CSI was given.

Study of Photovoltaic Pump System Based on Z-source Inverter;

Z-source inverter is an unique impedance network to take power source in coupling with converting circuit, thus it has the features either to make voltage up or voltage down which normal inverter does not have.

A direct peak DC-link Boost voltage fuzzy PID controller in Z-source inverter is proposed.

In this paper, a novel high-performance Z-source inverter is presented, which can overcome the inherent limitations and drawbacks of the traditional Z-source inverter (ZSI), while maintaining its all advantages (Buck-Boost character, higher reliability, etc.

With a unique X-type Z-source network, Z-source inverter can utilize the shoot-through state to boost the output voltage as the two-stage dc-ac inverter, which provides an attractive single-stage dc-ac conversion.

This paper presents a study of control methods for Z-source inverters used in photovoltaic pump system.

The VSCI with hysteresis-band is analyzed, a method to select the hysteresis-band width is proposed,and some experiment results are presented.
