PURPOSE:To reduce noise terminal voltage by observing a conductive noise of the electromagnetic wave noises generated from an inverter device, transmitted in an AC power supply line and a load side line, finally as the noise terminal voltage of an AC power supply, and changing ratio of the noise recirculated in an inverter device side to the noise of flowing out in an earth side, of the noises transmitted by a common mode in a load side of large influencing a noise terminal voltage value, even in a transmitting route of these conductive noises. CONSTITUTION:An inverter driving equipment formed by connecting a control device earth terminal of an inverter device 100 or the like to an earth terminal 111 of a load device of a motor 200 or the like with a conductor 113 of earth lead wire, braided wire, metal pipe, etc. |
