Common mode voltages generated by frequency converters are the cause of a large number of problems in electrical systems: EMC problems, bearing currents, unintentional tripping of RCCBs, faulty fieldbus communication, etc.
With all-pole sine filters, a large number of these problems can be solved, with additional positive effects for the design of the drive system.
