LCL filters have been specially designed to eliminate the harmonics from the current absorbed by 6-pulse power converters.


LCL filters are designed to reduce harmonics of current absorbed by power converters, with a rectifier input stage. (Frequency converters for motors, UPS, etc.). They are made of a parallel-series combination of reactors and capacitors adapted to reduce the THD (I) of rectifiers. They are designed to reduce the THD(I) to values of approximately 8%, in order to comply with IEC-61000-3.4 and IEEE-519 standards.
