摘要： A core has first to third magnetic leg portions. First and second windings wound on the first and second magnetic leg portions, respectively, are connected in series to constitute a first reactor. A third winding wound on the third magnetic leg portion constitutes a second reactor. A magnetic field produced from the first reactor and a magnetic field produced from the second reactor reinforce each other in the second magnetic leg portion, but weaken each other in the first magnetic leg portion. In accordance with increase in currents, the operation of the first and second reactors changes from a magnetically uncoupled mode in which the first and second reactors operate in a magnetically non-interfering state to a magnetically coupled mode in which the first and second reactors operate in a magnetically interfering state.

摘要： The present disclosure intends to simplify the wiring structure of a switching circuit included in a power conversion apparatus. A feedback signal acquisitor acquires a power supply feedback signal corresponding to electric power transmitted from a power supply switching unit to a load switching unit, via coupling conductive elements, from the power supply switching unit. Alternatively, the feedback signal acquisitor acquires a load feedback signal corresponding to the electric power, via coupling conductive elements, from the load switching unit. A command signal generator generates a power supply switching command signal and a load switching command signal. A command signal transmitter transmits the power supply switching command signal to the power supply switching unit via the coupling conductive elements, and transmits the load switching command signal to the load switching unit via the coupling conductive elements.

摘要： A magnetic component has a core on which windings are wound. The windings are electrically connected in series to constitute a coil of a first reactor. The winding constitutes a coil of a second reactor. The core has a leg portion on which the winding is wound, a leg portion on which the winding is wound, and a leg portion on which the winding is wound. When a current flows through the windings, magnetic fluxes produced from the windings, respectively, and flowing through the winding counteract each other. Furthermore, when a current flows through the winding, induced voltages produced from the windings, respectively, by the magnetic flux produced by the winding counteract each other.

摘要： A system includes energy modules that output power to an energy management bus based on load demands. An energy module includes energy cells enclosed within a module housing that provide power to the energy management bus and a driving system attached to the module housing that transports the energy module. The energy module includes a local controller that controls power output from the energy cells to the energy management bus, engages a self-driving mode in response to receiving a disconnection signal from a central controller, and controls movement of the energy module in the self-driving mode to a predetermined location via the driving system. The central controller receives a current module status from the energy modules and controls a configuration of the energy modules providing power to the energy management bus based on the current module status.

摘要： An operation mode selection unit selects an efficiency priority mode for minimizing the overall loss in a power supply system based on a load request voltage obtained in accordance with the condition of a load and on the conditions of DC power supplies, and generates a mode selection signal in accordance with the selection result. When SOC and/or output power have/has reached power supply restriction values in any DC power supply, an operation mode modification unit generates a final mode selection instructing signal so as to modify selection of the efficiency priority mode by the mode selection signal to select an operation mode in which power distribution between the DC power supplies can be controlled.
