The resisting device 23 includes a discharging means in fear of excessive charge in the storage battery by the regenerative power. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To solve the problem that size and cost of a motor-driven power supply are increased when providing the motor-driven power supply based on power required for a high-speed rotation of a rotor. SOLUTION: In power supply facilities for supplying power to an electromagnetic coil 2 of the rotor 1, a power supply is provided other than a current source 5 that can supply required power in low-speed rotation. The power supply takes out a current corresponding to an increment of power to be supplied to the electromagnetic coil from an electric double-layer capacitor 11 through a booster chopper 19 and a rectifying circuit 20 as a discharge current in the high-speed rotation of the rotor, and superimposes the discharge current on the output of the current source. The electric double-layer capacitor 11 of a power rectifier 12 is charged during operation stop and low-speed rotation of the rotor. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a DC power storage device, capable of restricting voltage fall of external wiring, absorbing regenerated power of an electric vehicle, and preventing loss of effect of regeneration of the electric vehicle without causing large-sizing or cost increase of a DC current storage device. SOLUTION: A terminal voltage (stand-by voltage) of an electric double layer capacitor EDLC is set to be close to an upper limit value in a rated voltage range of the external wiring at no-load time and normal load time of an electromotive system. When the external wiring voltage exceeds the upper limit voltage, regenerative power is absorbed by the electric double layer capacitor, while simultaneously, the electric vehicle takes regenerative current restricting action to prevent the terminal voltage of the electric double layer capacitor from exceeding the maximum voltage (prevention of loss of effect of regeneration). When the external wiring voltage becomes lower than a lowest voltage of the rated voltage range, the external wire voltage is prevented from becoming lower than the lower limit of the rated voltage range by use of discharge power from the electric double layer capacitor by pressure dropping action and pressure boosting action of a pressure adjusting chopper (restriction of voltage fall).
