- Abstract
Aiming at the problem of voltage reduction and voltage distortion due to the extensive use of inductive loads, and some shortcomings of existing reactive power compensation devices, a new AC-AC chopper based var compensator is proposed. The basic principles, compensation characteristics and topology of the Buck-Boost AC-AC chopper based var compensator are described, the mathematical model of Buck-Boost based on state-space equation is established, the relationship between duty ratio and compensation current is derived. The instantaneous reactive power theory and direct current control method are adopted to build a MATLAB model. The results indicate that the real-time compensation of reactive power in grid side can be realized by this var compensator based on a direct controlled Buck-Boost AC—AC chopper, it has potential application value.
