20090160252 | METHOD OF CONTROLLING HYBRID DC POWER SUPPLY SYSTEM - A fuel cell vehicle has a motor driven by an inverter and hybrid DC power supplies including a battery and a fuel cell for supplying electric power to the motor. For preventing a fuse connected to the battery from being blown out, when a motor current Im increases, a first source current flowing from the battery is limited to a range for not blowing out the fuse, and a generated current is increased as much as the first source current is limited. | 06-25-2009 |
20090166114 | METHOD OF DRIVING DC/DC CONVERTER, METHOD OF CONTROLLING DC/DC CONVERTER APPARATUS, METHOD OF CONTROLLING DRIVING OPERATION OF VEHICLE, AND METHOD OF DRIVING FUEL CELL SYSTEM - Under the same target voltage, a basic duty ratio depending on a target ON time is set, and prior and subsequent duty ratios before and after upper arm switching devices or lower arm switching devices are driven with the basic duty ratio are set as a basic duty ratio+α and a basic duty ratio−α, respectively. Gate drive signals, having the basic duty ratio and the prior and subsequent duty ratios, are supplied to the upper arm switching devices or to the lower arm switching devices, in order to turn on the upper arm switching devices or the lower arm switching devices. | 07-02-2009 |
20090179623 | METHOD OF CONTROLLING DC/DC CONVERTER APPARATUS - If a lower arm device connection period is non-zero in a previous switching cycle, a first dead time is prohibited from decreasing, and if the lower arm device connection period is zero, the first dead time is allowed to decrease, wherein the first dead time is the dead time provided after the lower arm device connection period in the previous switching cycle but before an upper arm device connection period in the current switching cycle. | 07-16-2009 |
20090212634 | METHOD OF CONTROLLING DC/DC CONVERTER, METHOD OF CONTROLLING DC/DC CONVERTER APPARATUS, AND METHOD OF CONTROLLING DRIVING OPERATION OF ELECTRIC VEHICLE - When a DC/DC converter switches between a primary voltage control mode, a secondary voltage control mode, and a current limiting mode as operation modes, an I-term resetting processor outputs an I term depending on the duty ratio in the operation mode before being switched to a PID processor. The PID processor performs a PID control process based on the input I term. A drive duty ratio setter outputs a drive duty ratio immediately after the control mode switching, which is substantially equal to the duty ratio in the operation mode before being switched. As a result, the duty ratios in the operation mode before being switched and the operation mode after being switched are made continuous with respect to each other. | 08-27-2009 |
20090230917 | METHOD OF PROTECTING ELECTRICITY STORAGE DEVICE IN HYBRID DC POWER SUPPLY SYSTEM - A method protects a battery in a fuel cell vehicle, in which an inverter-driven motor is supplied with electric power from the battery and a fuel cell. If a battery voltage of the battery falls outside of a prescribed range, a primary current and a secondary current that flow through the DC/DC converter, or currents in branch paths that correspond to the primary current and the secondary current, are reduced in order to limit a charging current flowing into the battery or a discharging current flowing from the battery. | 09-17-2009 |
20090243386 | METHOD OF CONTROLLING FUEL CELL VEHICLE AND METHOD OF CONTROLLING DC/DC CONVERTER APPARATUS - A controller is capable of executing direct couple control that directly couples a first power device and a second power device without causing a DC/DC converter to convert voltage. During the direct couple control, a drive signal that causes no voltage conversion is intermittently output to at least one of a plurality of switching devices. | 10-01-2009 |
20090284080 | METHOD OF CONTROLLING DC/DC CONVERTER, FUEL CELL VEHICLE FOR CARRYING OUT SUCH METHOD - A triangular-wave current flows through a reactor of a DC/DC converter for converting voltages between increased and reduced levels. Surges are reduced, which are developed in an output voltage serving as a control voltage when the triangular-wave current changes across a zero value at which the current direction is changed. When a primary current flowing through the reactor changes across | 11-19-2009 |
