Abstract: First windings of a first common mode transformer and second windings of a second common mode transformer are connected in series via connection lines. The windings are connected to an AC power supply via connection lines. The first windings are connected to a three-phase motor via connection lines, a converter, and an inverter. High-frequency leakage currents flowing in the connection lines are detected as a common mode voltage by a winding for common mode voltage detection. An output voltage is inputted via a filter to a voltage amplifier unit that amplifies the output voltage, and the amplified voltage is applied to a winding via a capacitor in substantially a same direction as a direction of the common mode voltage. As a result, leakage currents are reduced by induced voltages on the windings.

Abstract: Three-phase windings 11-13 and 21-23 of a first common-mode transformer 1 and a second common-mode transformer 2 are connected in series through connecting lines 8r-8t, respectively. The windings 11-13 are connected to an unillustrated AC power supply by connecting lines 91r-91t. The windings 21-23 are connected to a three-phase motor by connecting lines 93r-93t and through a converter and an inverter which are unillustrated. A winding 14 for common-mode voltage detection detects high-frequency leakage currents flowing through the connecting lines 91r-91t as a common-mode voltage V1, and an output voltage V2 obtained by voltage amplification by a voltage amplifier 3 is applied to a winding 24 for common-mode voltage application in such a manner that the output voltage V2 works in generally the same direction as the common-mode voltage V1, thereby canceling out the high-frequency leakage currents through the windings 21-23. Since a voltage amplification method is used, it is possible to reduce the high-frequency leakage currents with a simpler configuration as compared to a conventional current amplification method.

Abstract: In a system line for supplying power from an AC power source to a load through a converter and an inverter, a noise reduction unit is connected to a single connection line between the AC power source and the converter. In the noise reduction unit, a current transformer detects a noise current flowing through the connection line after converting it to a voltage, and the detected voltage V1 is supplied through a filter device to a voltage amplifier followed by being voltage-amplified and applied to a capacitor. The capacitor is connected to an injection point on the connection line, so that a high-frequency current in the same direction as the noise current is supplied to the converter from the connection line, to thereby reduce a high-frequency noise current at the AC power source side.

Abstract: In a system supplying power from an AC power supply to a three-phase motor via a converter and an inverter, a leakage current reducing apparatus is connected to a connection line between the AC power supply and the converter. A common mode transformer detects, as common mode voltage, common mode current flowing from the AC power supply to the connection line. The common mode voltage is inputted to a voltage amplifier via a filter apparatus. Output voltage obtained by voltage amplification passes through a capacitor and then is applied as an AC component to a neutral point of capacitors connected in a Y-connection fashion, so as to have the same phase as that of the common mode voltage. Thus, current having the same phase as that of the common mode current is supplied via the capacitors to the converter through the connection line, thereby reducing the common mode current.

Abstract: A process of detecting a defective recording element and a process of correcting the defective recording element are performed with appropriate processing loads. When the detection process and the correction processes are performed with small loads, for example, at a time of recording, a resolution used for reading an inspection pattern is set lower than that set in a case where the processes can be performed with small loads, for example, at down time before recording. The reading resolution to be set may be determined by an apparatus in accordance with a processing load or may be arbitrarily determined by a user.
