Abstract

The var compensation device is closely related to safe and stable operation of power grid

the research of var compensation has great significance to power system.In this paper

the topology structure and working principal of main circuit for ASVG inverter are briefly described.The method of carrier phase-shift control with adoption of multi-bridge parallel structure is put forward and a 12-bridges model is made.The comparison with the traditional converter structure and its corresponding PWM working mode have been carried out

and the DC side ripples

output current ripple are calculated by switch model.At last

it is validated by the use of MATLAB simulation software

which reflect the advantage of the new method.
