  • Patent number: 10380963
    Abstract: The present application includes a display driving circuit, driving method thereof, and display device. A voltage detection circuit is added to an existing display drive circuit, and the voltage detection circuit determines, according to a standard reference voltage signal outputted by a logic circuit, whether a reference voltage signal outputted by a power supply management circuit is abnormal. If the reference voltage signal is determined to be abnormal, the power supply management circuit is controlled to stop outputting the reference voltage signal, such that the power supply management circuit is in a static mode, and therefore, a display panel is in a constant white or constant black mode.

A charging circuit recharges the boost battery from the main battery during operation of the motor. The charging circuit also maintains a charge balance between the boost battery and the main battery when the two batteries have different chemistries. In one embodiment, participation of the boost battery in powering the electric motor can be controlled automatically according to sensed changes in the load.

    Abstract: A low voltage battery charger is provided that includes a fuel cell stack that generates electrical energy by a reaction of hydrogen and oxygen and an air blower that supplies air to the fuel cell stack. A high voltage DC converter converts an output voltage generated at the fuel cell stack to a high voltage. A high voltage battery is charged with the output voltage converted by the high voltage DC converter. A low voltage DC converter converts the output voltage generated at the fuel cell stack to a low voltage and a low voltage battery is charged with the output voltage converted by the low voltage DC converter. A controller then variably adjusts a charge voltage of the low voltage battery based on an air amount supplied to the fuel cell stack through the air blower.

  • Patent number: 9906035
    Abstract: A method of operating an electrical feeder permits the electrical feeder voltage to be maintained at the minimum voltage within a voltage range based upon dynamic grouping together of electrical generators on the electrical feeder with demand response loads on the electrical feeder. A method of assessing the proper operation of a voltage control device on the electrical feeder involves detecting a number of properties of the electrical power in the electrical feeder both prior to and subsequent to a change in an operational parameter of a voltage control device. An expected effect upon the electrical feeder of one or more distributed generators is filtered from this in order to determine a net effect of the voltage control device itself on the electrical feeder. Based upon the detected net effect and a predicted baseline effect for the voltage control device, it can be determined whether the voltage control device is functioning properly.

  • Patent number: 9876361
    Abstract: A method controls the operation of electric energy generators. A correction signal is sent to the control device and indicates a deviation of a current energy requirement of a supply network from a planned energy requirement. The control device transmits control signals to the energy generators, the correction signal being used for determining the control signals. To react to a correction signal, a control energy quantity is determined which indicates an energy quantity to be jointly provided by all energy generators, and a first energy generator is selected for providing a proportion of the control energy quantity. Further energy generators are sequentially selected, until the extent of the control energy quantity has been completely assigned to respective selected energy generators, and control signals are generated for the selected energy generators, which control signals indicate the proportions of the control energy quantity to be provided by the energy generators.

  • Patent number: 9831672
    Abstract: The disclosed embodiments provide a system that operates a power supply. During operation, the system disposes a first switching mechanism between a first output of a first power converter and two or more loads. Next, the system obtains two or more error signals for the two or more loads, wherein each error signal from the two or more error signals represents a difference between a load voltage of a load from the two or more loads and a first reference voltage for the load from a first set of reference voltages for driving the two or more loads using the first power converter. The system then uses the first switching mechanism to couple the load with a largest error signal from the two or more error signals to the first output.
