20090218983 | ELECTRICAL MANAGEMENT DEVICE FOR VEHICLE POWER SUPPLY - An electrical management device for a vehicle power supply that includes a single converter to minimize the number of components required to simultaneously control two energy sources, such as a photovoltaic source and a thermoelectric source, on board a motor vehicle that includes at least one electrical energy storage battery. | 09-03-2009 |
20100156172 | DEVICE AND METHOD FOR CONTROLLING A POWER SHUNT CIRCUIT, HYBRID VEHICLE HAVING SAME - A device for controlling a power shunt circuit of a hybrid vehicle, including inverters, including DC sides linked to a DC voltage storage unit and AC sides intended to be linked to polyphase electrical machines. The polyphase electrical machines are able to operate in engine/engine or generator/generator modes. A control unit controls chopping switches of the second inverter in a way that is temporally offset relative to chopping switches of the first inverter in such a case, the control unit of the inverters controlling their chopping switches by pulse width vector modulation. | 06-24-2010 |
20100179023 | ELECTRIC ENERGY EXCHANGE SYSTEM, IN PARTICULAR FOR A HYBRID VEHICLE - An electric energy exchange system between at least one motor-generator system and at least one storage member determining a continuous storage voltage between two branches of a bus circuit on which are connected in parallel a DC/DC converter, a filtering capacity, and a DC/AC converter connected on at least one motor-generator system. The system includes at least one thyristor connected as a bypass on the positive bus between the storage member and the output of the converter-voltage raiser to short-cut the converter, and a thyristor priming device to, based on the required voltage at the filtering capacity, determine at least in discharge the shorting of the converter-voltage raiser with direct passage of the current through the thyristor as long as the voltage of the filtering capacity, which is substantially equal to the storage member voltage, is sufficient for the electric machines to provide requested torque. The system can particularly be applied to a power-bypass hybrid vehicle, for continuous variation of transmission ratio. | 07-15-2010 |
