摘要
为了保证电压型PWM整流器有较好运行性能,对三相半桥可逆整流器的电流控制进行研究。提出一种电流跟踪性能好的滞环电流控制方法。滞环电流控制有较快的动态响应,不需要载波信号,误差可由滞环宽度调节。该方法可使电流控制精度很高,所以对三相半桥可逆整流器的滞环控制原理进行详细的分析,并建立了基于Matlab环境下的仿真模型。仿真结果验证了该设计方案的正确性。
In order to keep the voltage source rectifier＇s good performance, researching into the current control of three phase half - bridge reversible rectifier. This paper brings forward the control way of hysteresis - current with good track performance. Because of hysteresis -current control with delicacies dynamic correspondence, needless three with wave, adjustable- error by hysteresis - width and high precision, control principle of three phase half - bridge reversible rectifier is analyzed in this paper. Then simulation model is set up on the basis of Matlab background, the results of simulation verify the correctness of this scheme.
