  • Patent number: 12024033
    Abstract: An electric machine is coupled to at least the respective alternating current output terminal or to a plurality of alternating current output terminals of the inverter. The electric machine has a rotor with a rotational speed that is capable of converting rotational mechanical energy of the rotor into electrical energy at the direct current bus terminals until the rotational speed declines below a critical speed. In response to the detection of an impaired state of the battery, a controller is configured to provide control signals to switch or toggle the corresponding low-side switch or switches to manage the charging and discharging of the direct current (DC) bus voltage between a minimum DC voltage and a maximum DC voltage that define a range suitable for providing energy sufficient to power an electronic data processor and control logic of the controller.

  • Patent number: 11070138
    Abstract: Each one of the secondary converters has a corresponding transformer having a primary winding associated with a primary alternating current (AC) signal and a secondary winding associated with a secondary alternating current (AC) signal. A secondary controller provides secondary control signals to the secondary semiconductor switches of the secondary converters with one or more time-synchronized, target phase offsets with respect to an observed phase of the alternating current signal (e.g., primary alternating current signal or the secondary alternating current signal) to provide the target phase offset (or targeted phase offsets) commensurate with or sufficient to support a required electrical energy transfer from the primary controller to the corresponding secondary controller (or secondary controllers).
