  • Patent number: 12275493
    Abstract: A control device sets a second electricity control switch in an intermediate state in a process of switching a discharge battery for supplying a drive unit with an electrical current from a first battery to a second battery. Subsequently, when a comparative relationship between an electric potential of a smoothing capacitor and an electric potential of the second battery fulfills an intermediate state termination condition, the control device sets the second electricity control switch in a bidirectional conduction state. The intermediate state is when an electrical current flowing from the second battery to the drive unit is allowed, and an electrical current flowing from the drive unit to the second battery is inhibited. The bidirectional conduction state is when both of the electrical current flowing from the second battery to the drive unit and the electrical current flowing from the drive unit to the second battery are allowed.

  • Patent number: 12278590
    Abstract: The present disclosure contemplates a method for synchronizing a large number of generators on an AC bus by synchronizing each generator's output to a nominal output that is generated from a common external source. For example, each generator, using a high speed communication signal, can synchronize to a nominal output provided by a master generator, or centralized command module. In another example, each generator can generate its own nominal output referenced to a common external time signal, such as a global positioning system (GPS) signal, or other reference. By synchronizing independently of bus voltage and frequency, the generators are able to synchronize in parallel, instead of serially.

  • Patent number: 12255572
    Abstract: A method of detecting whether a stator distortion filter is connected to a generator of an electrical power system includes temporarily interrupting magnetic flux excitation of a generator of the electrical power system. The method also includes observing a sinusoidal waveform of one or more electrical feedbacks of the generator. Further, when the sinusoidal waveform persists longer than a predefined duration, the method includes determining that the passive load is connected to the generator of the electrical power system. When the sinusoidal waveform abruptly decays below a threshold in a time period less than the predefined duration, the method includes determining that the passive load is not connected to the generator of the electrical power system. Moreover, the method includes implementing a control action based on whether the passive load is connected to the generator of the electrical power system.
