摘要
This paper is established in a mathematical model of VIENNA rectifier in unbalanced grid. Then established the sliding mode controller in the two-phase static coordinate current loop and analyzed through Lyapunov stability criterion, in the voltage outer loop established backstepping controller based on Lyapunov stability criterion. To inhibit the current distortion caused the three-phase unbalance, the negative sequence current control strategy is used to calculate the instruction current in the two-phase static coordinate system. Finally, build simulation model to prove the validity of the VIENNA rectifier's three-phase power grid voltage unbalance strategy based on backstepping sliding mode control in the power grid unbalance state.
