41. Filters
 Line reactor filter : reduce current, reduce harmonics.
 Zero phase reactor filter: reduce radiated noise from the inverter wiring.
 EMI filter : remove electromagnetic noise on the power lines.
 Motor reactor: reduce frequency harmonics – increase in motor life time-motor
insulation protection.
 Dv/dt filter: minimize the peak voltage that occur in the motor terminals.
 Sine wave filter : reduce the noise that allow extend cables for long distance and
protect the motor from overheating.
