An Output Supply System (OSS) may comprise an Electric Power Generating System (EPGS) comprising a first Permanent Magnet Synchronous Machine (PMSM), a first three-phase multifunction converter, a first three-position switch, a battery management system, wherein the PMSM, the first three-phase multifunction converter, the first three-position switch, and the battery management system are in electronic communication, and a first tangible, non-transitory memory configured to communicate with a first controller, the first tangible, non-transitory memory having instructions stored thereon that, in response to execution by the first controller, cause the first controller to perform operations.

In one embodiment, the disclosure provides a load control system for providing power to one or more electronic devices, such as a lightbulb. The load control system includes a line terminal, a load terminal, an input interface, and a power output controller. The power output controller is electrically coupled to the line terminal and the load terminal. The power output controller is configured to receive a nominal line voltage at the line terminal, and is further configured to provide a nominal load voltage at the load terminal. The power output controller is configured to receive an input gesture from the input interface, and generate a formatted control signal based at least in part on the input gesture, and an identity of a first controlled device electrically coupled to the load terminal. The power output controller is configured to transmit the formatted control signal to the first controlled device.

A power supply comprises a DC power source, first and second DC/DC converters, and a protection circuit. The DC power source provides DC power at a variable bulk voltage. The first DC/DC converter converts the DC power from the DC power source to DC power at a high voltage suitable for powering a high-voltage load. The second DC/DC converter receives DC power from the first DC/DC converter, converts the received DC power to DC power at a low voltage, and delivers the DC power at the low voltage to a low-voltage load. The protection circuit selectively transfers DC power from the first DC/DC converter to the high-voltage load. The DC power source may be an AC/DC converter receiving AC power from a power generator driven by an aircraft engine.

A method for a direct current (DC) power distribution arrangement and a direct current (DC) power distribution arrangement, comprising a plurality of DC power distribution subsystems. Each DC power distribution subsystem comprises an inverter unit (INU) configured to operate as a subsystem-specific circuit breaker for intercoupling/separating the DC power distribution subsystem to/from the rest of the DC power distribution arrangement.

A power tool includes a motor and control means for controlling the motor. The motor is capable of being driven by power supplied from a battery pack including a battery cell. The control means is configured to continue to rotate the motor even when a motor-halt signal is inputted from the battery pack. With this structure, the power tool can be used continuously without need to halt rotation of the motor, even when receiving a halt signal, such as an overdischarge detection signal or an overcurrent detection signal.

Primary-side windings of the transformers (T1,T2,T3) are connected in parallel to each other. A switch (SW) turns on/off primary side currents of the transformers (T1,T2,T3). Each transformer (T1,T2,T3) includes a plurality of secondary-side windings.

There is an appliance for an aircraft. The appliance is configured to be powered by high voltage direct current, HVDC, power at its input.

An optimal control strategy for a distributed low voltage system with bidirectional DC/DC converters is provided. A vehicle system includes DC/DC converters configured to receive electrical currents from high voltage battery modules and output regulating electrical currents to a low voltage battery. The vehicle system includes a control system coupled to the DC/DC converters, the high voltage battery modules, and the low voltage battery, where the control system is configured to control the DC/DC converters to recirculate one or more of the electrical currents back to one or more of the high voltage battery modules in order to balance states of charge in the high voltage battery modules.

A power management system for dispensers is described. The system includes a controller connected to a lower power zero net voltage (ZNV) power source. A power rectification circuit (PRC) converts ZNV power to higher voltage direct current (HVDC) power. An energy storage system connected to the HVDC power source receives and stores HVDC power within the energy storage system which is selectively provided to a dispenser motor load connected to the energy storage system. The system provides an effective solution to the problem of transferring power from a low power battery source on a disposable product to a dispenser as well as providing a system that minimizes corrosion at the electrical interface between the disposable product and the dispenser particularly in higher humidity environments.

A method and device for wireless data transmission are described. A device receives sets of sensor data associated with respective sensor measurements for a vehicle. The device determines a priority for each of the sets of sensor data based on an amount of data stored for that sensor measurement in a number of data queues, and selectively stores each of the sets of sensor data in one of the data queues based on a threshold data throughput rate of a wireless network and the priority of each set of sensor data. The device transmits, to a second computing device via the wireless network, at least some of the sets of sensor data from the data queues based on a current data throughput rate of the wireless network and a priority level of each of the data queues.
