Optimized design of LCL output filter for grid-side PWM rectifier
摘要
Abstract
This paper proposes a design method for an LCL filter in grid-side PWM rectifier, then it is modeled. The research in single-phase model transfer function of LCL filter is made to obtain the relation between resonance frequency, harmonic current amplitude attenuation factor and factor r-the ratio between grid-side and rectifier-side inductance. The total inductance, capacitance of filter and r can be selected by analyzing the change tendency of the variable relation figures. The analysis results indicate that the lower limit of the total inductance and capacitance of filter are determined by resonance frequency. Finally, a designed example is reported, and the validity of this method is tested by simulation.关键词
