The Application of General Inverter in Milling Planer;

The control method of using general inverter to keep the tension of wire and cable constant;

Armed at applying the general inverter to photovohaie pump system,the structure of photovoltaic pump system and general inverter is introduced.

Multi-purpose converter have been designed versatilely and flexibly and need to order parmeter when applied in different occasions.

The results demonstrate that the de- veloped operation panels are feasible and usable,and also the way is used for the multi-purpose converter successfully.

Researches on the power factor based on general converter energy-saving;

Energy-saving fundamentals of capacity compensation and general converter and its selection;

This paper introduce briefly the limitation of common general converter,analyzes the control tactics of high performance general converter,states the application and development situation of the vector control and direct torque control,and looks forward to the prospects of the non-speed sensor control.
