<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This paper introduces a new iterative design procedure of <formula formulatype="inline"><tex Notation="TeX">$L$</tex> </formula> and <formula formulatype="inline"><tex Notation="TeX">$LCL$</tex></formula> filters for low-voltage active-front-end PWM two-level voltage source converters. The analytical expression of the converter harmonic voltages by Bessel functions is applied to design the filter parameters for defined maximum grid current harmonics. Different filter designs are derived for various resonance frequencies and inductance split factors of <formula formulatype="inline"> <tex Notation="TeX">$LCL$</tex></formula> filter. The minimum amount of stored energy of passive components is used to select a final filter design. A voltage-oriented control scheme, including active damping, is applied in the (400 V and 50 kVA) experimental setup. Both simulation and experimental investigations are presented to verify the accuracy of the filter design procedure. Finally, the steady state and transient performance of the active front end with different <formula formulatype="inline"><tex Notation="TeX">$LCL$</tex></formula> filters are depicted. </para>
