| 20090058337 | CONTROL DEVICE AND CONTROL METHOD OF BOOST CONVERTER - A control device of a boost converter which includes: an inverter circuit which controls switching to apply current to a stator winding of respective phases of a multi-phase brushless DC motor; and a boost circuit which is provided on an input side of the inverter circuit and has at least a reactor and a switching element, and controls ON and OFF states of the switching element of the boost circuit on the basis of a boost voltage command which is a command for boost voltage output from the boost circuit, the control device is provided with a boost voltage command setting unit which sets the boost voltage command on the basis of counter electromotive voltage of the brushless DC motor and a torque command for the brushless DC motor. | 03-05-2009 |
| 20110109274 | CHARGE AND DISCHARGE CONTROL APPARATUS AND CHARGE AND DISCHARGE CONTROL METHOD FOR SECONDARY BATTERY - A charge and discharge control apparatus for a secondary battery, which uses feedforward control and feedback control in combination to execute charge and discharge control over the secondary battery, includes: a feedforward control unit that executes the feedforward control; a feedback control unit that executes the feedback control; and a control mode changing unit that changes a control mode between the feedforward control and the feedback control. The feedforward control unit controls at least one of a charging electric power and a discharging electric power on the basis of a predetermined permissible electric power value. When the permissible electric power value is lower than or equal to a predetermined value, the control mode changing unit prohibits the feedforward control, and changes the control mode so as to control at least one of the charging electric power and the discharging electric power through the feedback control. | 05-12-2011 |

| 20100248082 | FUEL CELL SYSTEM - A fuel cell system includes: a fuel cell; a fuel tank provided opposite to the fuel cell and adapted to contain hydrogen absorbing alloy; and a supply channel adapted to supply hydrogen discharged from the hydrogen absorbing alloy to the fuel cell. The fuel cartridge is provided with a discharging unit adapted to discharge hydrogen from the hydrogen absorbing alloy to the supply channel. The discharging unit is provided opposite to the center of the fuel cell. | 09-30-2010 |
| 20110189568 | FUEL CELL SYSTEM - A fuel cell system has two fuel cell modules each arranged in a plane. In the fuel cell modules each including a plurality of membrane electrode assemblies arranged in a plane, hydrogen stored in a fuel cartridge is fed to anodes of the fuel cell modules. A control unit performs control of connecting the two fuel cell modules alternately to an external load, when the external load connected to a fuel cell system is within a prescribed threshold value and at least one of the temperature of one of the fuel cell modules and the temperature of the other of the fuel cell modules is at or below a prescribed threshold temperature. | 08-04-2011 |
