Using a novel thyristor triggering device, the automatic electronic load is an efficient solution for overturning of active inverter.

Active inverter is very popular in power electronics field in recent years because it can realize power recycling.

It associates the traditional linear regulate technique with the rectification and active inversion tech.

A method that adopts double level converter circuit to have made a new style of discharging device:"single- phase active inverter battery feedback discharging device",is instruduced.

The system is operated with unity power factor in the side of AC line no matter in rectifier mode or active inverter mode.

Now that energy save is being advocated, active inverter is getting more and more widely used.

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.
