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 ensure and facilitate start and stop of a device, restart after a long power interruption (a complete power interruption) uncompensable in the specification, and to rapidly settle a condition for the instantaneous voltage-drop. SOLUTION: During the device operation, power is cut off at a high-speed by a high-speed switch 15 at the instantaneous voltage-drop while an instantaneous voltage-drop stand-by state is entered wherein a power can be supplied from an inverter 19 by a controller 25 while using a full-charged electric double-layer capacitor 20 as a power source. When the device is stopped, a constant-power discharge for the electric double-layer capacitor 20 and further a complete discharge are conducted without interrupting the power supply to a load from a system power source. In the constant-power discharge, the power is regenerated or regenerated to the power source side as the power for the load, and completely discharged after the electric double-layer capacitor is regenerated approximately. At a restart after the complete power interruption, an instantaneous voltage-drop compensating stand-by operating state is automatically restored without manual operation, and the device is restarted quickly without completely discharging the electric double-layer capacitor.

摘要翻译：要解决的问题：为了确保和促进设备的启动和停止，在规格中无法补偿的长时间断电（完全断电）后重新启动，并快速建立瞬时电压降的条件。
解决方案：在器件操作期间，在瞬时电压降下，高速开关15以高速切断电源，同时进入瞬时降压待机状态，其中可以提供电力在使用全充电双电层电容器20作为电源的同时由控制器25从逆变器19输出。当器件停止时，不会中断来自系统电源的负载的电力供应，进行双电层电容器20的恒定功率放电以及进一步的完全放电。在恒功率放电中，作为负载的功率将功率再生或再生成电源侧，并且在双电层电容器近似再生后完全放电。在完全断电后重新启动，瞬时降压补偿待机工作状态自动恢复，无需手动操作，器件快速重新启动，而不必完全放电双电层电容器。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To shorten the discharge time during discharge of voltage of an electric double layer capacitor for maintenance or the like. SOLUTION: In a condition that a breaker 8 is opened, a switch 9 is switched on, and a switch 11 is opened, a power converter 6 is operated independently so as to consume the power charged in an electric double layer capacitor 10 as the loss of the power converter 6. When the voltage of the capacitor drops to a predetermined value, the power converter 6 is stopped and the switch 11 for capacitor discharge is switched on so as to let a current flow from the electric double layer capacitor 10 to a discharge resistor 12 and discharge the power charged in the electric double layer capacitor 10. Since the capacitor voltage is dropped before letting flow a current to the discharge resistor 12, the discharge time shortens. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：为了缩短用于维护的双电层电容器的电压放电时间等。解决方案：在断路器8断开的情况下，开关9接通，开关11断开，功率转换器6独立地工作，以消耗充电在双电层电容器10中的电力作为功率转换器6的损耗。当电容器的电压下降到预定值时，功率转换器6停止，用于电容器放电的开关11接通，以使电流从双电层电容器流出 10放电到放电电阻器12，并且对双电层电容器10中的电荷进行放电。由于在使放电电阻器12流过电流之前电容器电压下降，所以放电时间缩短。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an uninterruptible power supply unit which is longer in service life and a compact type, making use of dc power from a distributed power supply unit. SOLUTION: The uninterruptible power supply unit once converts AC power of a commercial electric power system into dc power by a rectifier to output to a DC circuit, then converts the DC power to the AC power by an inverter to supply to a critical load, wherein the external DC power is supplied to the DC circuit through a diode in which a cathode is connected to the DC circuit, while the rectifier outputs the DC power of a voltage which is higher than that of the DC power supplied from the external source, when the commercial electric power system is normal.

摘要： PROBLEM TO BE SOLVED: To solve a problem of an uninterruptible power supply employing a secondary battery for storing power that a switch circuit must be connected in series with the secondary battery in order to protect it against overcharge because charge/discharge control is performed based on a time schedule. SOLUTION: The switch circuit can be eliminated by controlling the passing power of a converter to match the load power of an inverter or to deviate slightly therefrom and generating a PCS charge/discharge command such that a secondary battery is brought into zero current state or faint discharge state thereby preventing overcharge.

摘要： PROBLEM TO BE SOLVED: To downsize the constitution of a device at large by contriving the method of charging an electric double layer capacitor before its initial start thereby reducing the capacitor of a chopper. SOLUTION: In a condition that a breaker 8 is opened and a switch 9 is opened, a switch 12 is switched on to charge a DC capacitor 7 by means of a precharge circuit 11. Then, the breaker 8 is switched on and the switch 12 is opened, and a capacitor 10 is charged by a chopper 13 while controlling the DC voltage of the power converter 6 to be constant. Then, the chopper 13 is stopped and the switch 9 is switched on, and a capacitor 10 is charged with DC power that is obtained by operating the power converter 6 as a converter. Since the charge by the chopper 13 is only in the initial stage of the charge, the chopper 13 gets off with small capacity, and the device configuration is downsized. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：为了通过在初始启动之前设计双电层电容器的充电方法来缩小装置的结构，从而减少了斩波器的电容器。解决方案：在断路器8断开并且开关9断开的情况下，开关12接通以通过预充电电路11对直流电容器7充电。然后断路器8接通，开关12断开，电容器10由斩波器13充电，同时将电力转换器6的直流电压控制为恒定。然后，断路器13停止并且开关9接通，并且电容器10充电具有通过操作电力转换器6作为转换器而获得的DC电力。由于斩波器13的充电仅在充电的初始阶段，所以斩波器13以小的容量下降，并且器件结构被小型化。版权所有（C）2006，JPO＆NCIPI
