摘要
用状态空间法建立三相SVPWM整流器VSR的数学模型,并根据此模型建立了三相SVPWM整流器的等效电路模型,在理论上分析了该模型的交流侧和直流侧的稳态工作情况,分析了交流侧电感和直流侧电容对整个主电路起着至关重要的作用,并提出了完整的主电路参数计算方法。
A methematical model of three-phase SVPWM rectifier is introduced. The method takes restrain harmonic and hi-directional power flow characteristic into consideration, which is key to accomplishing the whole task of three phase PWM rectifier system. The analysis shows that the principle is useful for deciding the value of the circuit parameter.
