一种电流控制型并联24脉波整流器

A Current-controlled Parallel 24-pulse Rectifier

为提高并联12脉波整流器谐波抑制能力及输出电流的动态性能,提出一种基于电流控制的双通道可控24脉波整流器。该整流器由并联12脉波整流器、带副边的平衡电抗器及单相整流桥组成,在输出脉波数倍增为24脉波的基础上,电流控制策略实现输出电流快速响应及可调。搭建MATLAB仿真模型进行全面仿真,验证了该方案有着常规24脉波整流器的谐波抑制能力的同时,带电流控制策略的电路具有更好的动态性能。

To enhance the harmonic suppression capability and dynamic performance of the parallel 12-pulse rectifier,a current-controlled dual-channel controllable 24-pulse rectifier is proposed.This rectifier consists of a parallel 12-pulse rectifier,a balanced reactance with a secondary side,and a single-phase rectifier bridge.Building upon the multiplication of output pulses to 24 pulses,the current control strategy facilitates rapid response and adjustability of the output current.A comprehensive simulation is conducted using MATLAB to validate the proposed approach.Results demonstrate that while maintaining conventional harmonic suppression capability comparable to that of a standard 24-pulse rectifier,the circuit with current control strategy exhibits superior dynamic performance.
