Repetitive impulse voltage generator development and waveform analysis for testing insulation dignity of inverter-fed low voltage motor

摘要

The authors have developed a repetitive impulse generator which meets conditions required by IEC/IS 60034-18-41 for inverter-fed low voltage motor. This paper deals with experimental and analytical investigation on impulse voltage waveform generated with our developed impulse generator under the voltage application to a low voltage inverter-fed motor. A relatively good agreement is obtained between the experimental and analytical waveforms.
