要約(英語): An increasing number of voltage-driven-type PWM inverters have begun to be used recently for electrical equipment in buildings owing to energy conservation considerations. However, common-mode currents originate from this type of inverters, and problems due to such common-mode currents flowing in grounding systems of buildings have increased with their increased use. While it is necessary to study countermeasures to overcome these problems by considering the entire circuit in question (since common-mode currents flow in the whole circuit including power-supply and grounding systems), there seem to have been very few such studies. In this study, the author constructed a test circuit comprising a PWM inverter, an induction motor, and grounding electrodes, and he studied measures to suppress common-mode currents by using shielded cables and a grounding system. He also studied a method for grounding the shielding of the shielded cables used for the power supply from the inverter to the motor suppressing common-mode currents.
