Abstract
For wireless parallel inverters system, there is a high requirement of control precision: otherwise current-sharing effect would be very poor. Based on this characteristic of wireless paralleling technology, this paper represents the combination control method of repetitive control with PI-P voltage and current double close loop control (abbreviation as PI control) in this system. This control method, which combines with PI control, has relatively faster dynamic response speed, improves not only the capacity with nonlinear load and parallel circulation characteristics by characteristics of repetitive control, but also the steady state control accuracy of the system, meanwhile reduces the harmonic content. Its an outstanding composite control method. This paper proves the feasibility and superiority of this method by MATLAB simulation.
