Regenerative harmonic filter (400V/50Hz)
Description
LCL filters are used in particular with regenerative converters (AFE), but also with converters for renewable energies. The main task of this filter is to eliminate the PWM frequencies, with the aim of not polluting the supply network when feeding in the energy.
