    Abstract: An example according to one embodiment includes a first coil and a second coil spaced apart therefrom. The system is supplied with power from a primary-side circuit to a secondary-side circuit and vice versa. The primary-side circuit includes the first coil. The secondary-side circuit includes the second coil. The primary-side circuit connects to a first converter that converts direct current into alternating current and vice versa. The first converter connects to second converter that converts direct current into alternating current and vice versa, and the second converter further connects to a commercial power supply. The secondary-side circuit connects to third converter that converts direct current into alternating current and vice versa, and the third converter further connects to direct current power supply of a moving body. Bidirectional power transfer is performed only by a switching operation of the first converter, the second converter, and the third converter.

  • Publication number: 20140239735
    Abstract: In an example of a system, power is transferred from a transmission coil to a reception coil by electromagnetic induction. A detecting unit calculates a difference between a standard value and a measured value, detects presence of a metallic foreign object on the transmission coil based on the difference, and outputs a signal when the metallic foreign object is detected. The standard value is obtained by supplying electrical power to the transmission coil when a metallic foreign object is absent on the transmission coil. The measured value is obtained by supplying electrical power to the transmission coil. If PIN0 represents input power of the transmission coil, PL0 represents output power of the reception coil, Pc1 represents copper loss of the transmission coil, and Pc2, represents copper loss of the reception coil, the detecting unit uses a value expressed by (PIN0-PL0-Pc1-Pc2) as the standard value and the measured value.

  • Publication number: 20130313912
    Abstract: According to one embodiment, contactless power transfer apparatus includes: transmission coil; primary capacitor; reception coil opposing transmission coil through gap; and secondary capacitor. Specification of frequency of the transmission coil and that of the reception coil are equal. At least one of electrical power specification and gap length specification of the transmission coil differ from the reception coil. When the electrical power specification of the power transmission coil differ from that of the power reception coil, the power is supplied from the transmission coil to the reception coil by using smaller one of the power of the transmission coil and of the reception coil as maximum power. When the gap length specification of the transmission coil differs from that of the reception coil, the transmission coil opposes the reception coil through the gap length, which is the specification of the transmission coil.

  • Patent number: 8164925
    Abstract: [Problems] To provide a non-contact power feeder that is high efficient and high power factor and has no load dependence. [Means for Solving Problems] A series capacitor Cs1 is connected to a primary winding 1 driven by an AC power supply 3 and a parallel capacitor Cp2 is connected to a secondary winding 2. The capacitance Cp is set to Cp?1/{2?f0×(x0+x2)} and the capacitance Cs converted to the primary side is set to Cs?(x0+x2)/{2?f0×(x0×x1+x1×x2+x2×x0)}, where f0 is the frequency of the power supply, x1 is a primary leakage reactance of the primary winding 1, x2 is a secondary leakage reactance of the secondary winding 2 converted to the primary side and x0 is an excitation reactance converted to the primary side. By setting Cp and Cs to the above values, the transformer of the non-contact power feeder is substantially equivalent to an ideal transformer. If it is driven by a voltage type converter, the output voltage (=load voltage) becomes substantially constant voltage regardless of the load.

  • Publication number: 20100141220
    Abstract: [Problems] To provide a series electric double-layer capacitor device having a simple structure eliminating nonuniform voltages induced among electric double-layer capacitors (C1 to C6). [Means for Solving Problems] A series electric double-layer capacitor device comprises 2n capacitors (C1 to C6), 2n diodes (D1 to D6), a transformer (T1), and an inverter (31). Secondary wirings (N1 to N3) of the transformer supply the induced voltages to a capacitor module (30) composed of sets of two capacitors and two diodes. The capacitors are charged when the diodes included in the capacitor module are conductive. The series electric double-layer capacitor device further comprises voltage adjusting means (32) for changing the DC voltage level between terminals (1, 2), and the inverter converts the voltage-changed DC voltage into an AC voltage. A voltage for canceling the forward voltage drops of the diodes is added to the induced voltages of the secondary wirings by the operation of the voltage adjusting means.

  • Patent number: 7509302
    Abstract: The present invention provides a high-performance storage access environment to a user who moves around a wide area, while increasing the fault resistance of the system. A plurality of network storages (volumes) is assigned to the user. Then, at the occasion of logging in to a volume by the user, the volume that can be accessed with high performance from a position he made access is located. Addresses at a computer with which user makes access are associated with addresses of the volumes provided by a storage device in advance in an assigned volume management table so as to increase access performance. Then, a management server performs control so that the address of the volume associated with the user access position is returned as a response, at the time of logging in.

  • Patent number: 7366867
    Abstract: A burden placed on an administrator in creating a volume is reduced. An evaluation hint value and a performance hint value are employed as hint values for each hint. The evaluation hint value is determined by the administrator considering a service usage and the like of the service server 1 to which the volume is allocated. The performance hint value is used to determine a performance and a setting of the volume to be created in the storage system 3. The management server 2 has a conversion table indicating a correspondence between the evaluation hint value defined considering the hardware configuration and the performance hint value, with respect to each storage system 3. The management server 2 converts the evaluation hint value designated by the administrator to a performance hint value, by use of the conversion table associated with the storage system to which the volume is to be created, and the management server creates the volume in the storage system 3 according to the performance value.
