Control Strategy of Variable Frequency Speed Regulation System Based on Multi-Drive

提出了一种基于多驱动的变频调速系统,该系统拓扑电路为交-直-交结构型式,控制性能为交-交直接变换.零电流换流策略和PWM控制策略可以得到好的输入电流和输出电压波形,实现安全换流.仿真的实验结果表明,基于多驱动变频调速系统的控制与策略是正确的.

This paper presents a multi drive variable frequency speed control system.The topology of the system is AC-DC-AC structure,and the control performance is AC-AC direct conversion.Zero current commutation strategy and PWM control strategy can get good input current and output voltage waveform,and realize safe commutation.In the following,the correctness of the theory proposed in this paper is proved by the simulation results.
