中文摘要	LCL-filter is used in three-phase PWM (pulse width modulation) rectifier instead of traditional L-filter to attenuate high frequency harmonics. A new method is provided to simplify the parameter design of LCL. The converter-side inductor, AC capacitor and grid-side inductor are calculated based on the maximum allowable current ripple at converter side, the maximum reactive power to be absorbed and the maximum allowable current ripple at grid side respectively. An accurate simulation model is established with the consideration of the time delay induced by controllers and the system stability is analyzed in z- plane to optimize the damping resistor. An example is given. Comparison of PWM rectifiers between L-filter and LCL-filter are carried out by experiments, showing the advantages of the latter. Experimental results validate the correctness of proposed methods for parameter design and stability analysis.
