| Abstract |
Inverter output harmonics create great amount of losses in a solid-rotor induction motor. An output
filter for a PWM-inverter is introduced to smoothen the inverter output wave forms. The efficiency of
the solid-rotor induction motor will increase remarkably. The filter is designed so that it also
compensates the magnetising current of the motor, thus the poor power factor of the solid-rotor
induction motor does not affect to inverter sizing. The EMC-matters, voltage stress in stator windings
and bearing currents are also examined. This paper focuses on the filter component selection and the
filter design. Measurements of a 12 kW, 13500 rpm prototype are given. |
