应用于AC/AC变换的M3C系统控制策略
M3C System Control Strategy Applied to AC/AC Conversion
摘要
Abstract
Modular multilevel matrix converter(M3C)is a multilevel topology that can directly realize AC-AC conversion,which has good application prospects in high-voltage transmission systems and DC distribution systems,but the existence of bridge-arm circulating channels inside the M3C leads to a very complex control structure.For this reason,a hierarchical system control strategy was proposed.First,the mathematical model of the M3C was derived based on the conventional double αβ0 coordinate transformation.Then,a dual-loop control structure consisting of an outer-loop and an inner-loop controller was employed in the M3C,which is usually employed in voltage source converters.In addition,in order to suppress the loop current component inside the system,a bridge arm energy equalization control strategy based on double αβ0 transform decoupling was proposed,through which the capacitive voltage control between the bridge arm and the bridge arm was realized by this control and carrier phase shift modulation.Ultimately,the simulation model and physical prototype were constructed,and the outcomes validated the viability of the proposed control strategy for the M3C system.关键词
