采用DRC-SPWM的VIENNA整流器在dq坐标系下的数学模型
|
摘要
针对采用双斜坡比较载波调制(DRC-SPWM)的三电平VIENNA整流器在dq坐标系下进行控制时,控制环路中出现Park变换和反Park变换导致系统传递函数无法写出的问题,提出了一种将载波调制变换到dq坐标系下的处理方法,建立了基于MIMO状态空间的LCL滤波器的数学模型,得出了VIENNA整流器完整的数学模型,并对系统的控制环路进行了设计。最后搭建了仿真平台和实验样机,仿真结果和实验结果验证了VIENNA整流器在dq坐标系下数学模型及控制环路设计的合理性及正确性。该方法将VIENNA整流器在dq坐标系下的数学模型完全量化表达,简化了VIENNA整流器控制环路的设计,可以广泛应用于开关电源的输入整流模块中。
System transfer function cannot be written due to the Park transformation and the anti-park transformation in the control loop when the three-level VIENNA rectifier with double ramp comparison carrier modulation is controlled in dq coordinate. To solve this problem,a method for the transformation of carrier modulation to dq coordinate is proposed. A mathematical model of LCL filter based on MIMO state space was established,the complete mathematical model of VIENNA rectifier was obtained,and the control loop was designed. Finally,the simulation platform and experimental prototype were built. The simulation results and experimental results verify the rationality and correctness of the mathematical model and control loop design of the VIENNA rectifier in dq coordinate system. The mathematical model of VIENNA rectifier in dq coordinate system is expressed in this method,and the control loop design of VIENNA rectifier is simplified and can be widely used in the input rectifier module of switching power supply.
