摘　　要：该文对基于间接电流控制三相电压型整流器的数学模型和控制策略进行研究。提出以整流器前端电压滞后角ξ为控制变量的新型相位幅值控制方案。该方案基本思想是利用滞后角ξ和调制比m_r的耦合关系来减少系统设计的复杂程度。通过建立的系统小信号模型完成闭环设计。该方案控制思想明了,应用方便,有一定的应用前景。通过仿真和实验验证系统有良好的控制性能。The paper presented a mathematic model and control strategy on a three-phase voltage type rectifier under indirect current control. A new phase and amplitude control scheme is put forward by using a rectifier front voltage lag angle ξas control variable. The basic concept of the scheme is to utilize a coupling relation between the lag angleξ and modulation rate mr and resulting in reducing the complexity of system design. Through establishing small signal model, a close loop design is completed. The new model has a clear concept and applicability in practice, and the simulation and experiment results show that the system has a high quality in performance.
