摘要： An inductor array that includes a plurality of inductors where adjacent inductors share a core piece and thus a flux path to reduce the size and weight of the array. In one embodiment, the shared core pieces are formed as back-to-back U-shaped members defining an indented region at the center of the core piece. In another embodiment, a plurality of small block-shaped center core pieces in each inductor defines a plurality of gaps therebetween.

摘要： Systems and methods are provided for regulating the state of charge of a battery. An exemplary electrical system includes a fuel cell coupled to a bus and a battery coupled to the bus via a switching arrangement coupled to a capacitor. An exemplary method for operating the electrical system involves operating the switching arrangement such that a voltage of the battery is substantially equal to a voltage of the fuel cell when a state of charge of the battery is greater than a lower threshold value and less than an upper threshold value, and operating the switching arrangement to couple the capacitor electrically in series between the battery and the bus when the state of charge of the battery is not between the lower threshold value and the upper threshold value.

摘要： Systems and methods are provided for discharging a high-voltage bus using semiconductor devices. A discharge system for a first voltage rail and a second voltage rail comprises a first semiconductor device coupled to a first voltage rail and a second semiconductor device coupled between the first semiconductor device and a second voltage rail. A control circuit is coupled to the first semiconductor device and the second semiconductor device. In response to a discharge condition, the control circuit is configured to activate the first semiconductor device and gradually activate the second semiconductor device, such that the energy potential between the first voltage rail and the second voltage rail is gradually dissipated through the semiconductor devices.
