Compared to conventional L filters, LCL filters and LLCL filters have better high-frequency harmonic attenuation ability with less total inductance. However, one or two more magnetic cores are commonly demanded for grid-side and paralleled trap inductors. To further reduce the weight and volume of filter inductors, magnetic integration technique is an… CONTINUE READING
