Abstract: The charging and/or discharging of a set of swappable battery modules in a battery system is carried out automatically using a set of charging and/or discharging control switches linked in a sequential charging and/or a discharging control chain. The charging and discharging of the set of battery modules can be done sequentially or in parallel, and is hardware-based with minimal software/firmware involvement. The system is scalable and automatically reconfigurable for use in an infrastructure and/or in an electric vehicle. The swappable battery modules may be positioned in the battery slots or butted together in the battery system.

Abstract: A single fire-wire phase-front dynamic AC power fetching module, comprising: two series-connected type synchronous power fetching circuits connected in parallel, and an electronic switch connected thereto, one series-connected type synchronous power fetching circuit is used to perform positive phase AC power fetching, while the other series-connected type synchronous power fetching circuit is used to perform negative phase AC power fetching. The electronic switch is formed by a relay or a silicon control crystal (TRIAC) controlled by an MCU microprocessor. As such, through adopting bi-directional dynamic full-bridge type power fetching, for a single fire wire, it is able to perform power fetching twice in a cycle. The duration of power fetching can be regulated automatically depending on the load, to compensate for the power, and supply it to an outside circuit as the basic power supply.

Abstract: A rectifier comprising a chain of transistors for RF-DC conversion. In order to compensate for the thresholds of the transistors, each transistor can be connected to a junction earlier or later in the chain. By using both p-type and n-type transistors in the same chain, the different types of transistors can be compensated in different directions allowing more transistors to be compensated. Additional transistors connected to the gates of transistors of the main chain can allow the transistors of the main chain to be forward compensated at one part of the input cycle and backward compensated in another part to minimize both the voltage threshold of the rectifier and the leakage current. The line for compensation of the voltage threshold during forward conduction can comprise a solid line or a transistor, and if a transistor is used it may be diode-connected.

Abstract: An apparatus for processing electric power includes a power-converter having a path for power flow between first and second power-converter terminals. During operation the first and second power-converter terminals are maintained at respective first and second voltages. Two regulating-circuits and a switching network are disposed on the path. The first regulating-circuit includes a magnetic-storage element and a first-regulating-circuit terminal. The second regulating-circuit includes a second-regulating-circuit terminal. The first-regulating-circuit terminal is connected to the first switching-network-terminal and the second-regulating-circuit terminal is connected to the second switching-network-terminal. The switching network is transitions between a first switch-configuration and a second switch-configuration. In the first switch-configuration, charge accumulates in the first charge-storage-element at a first rate. Conversely, in the second switch-configuration, charge is depleted from the first charge-storage-element at a second rate. These rates are constrained by the magnetic-storage element.

The circuit, in at least one embodiment, includes a line-side converter that is coupled to a capacitor. The line-side converter includes at least two series connections, each including at least two power semiconductor elements, and each of the at least two series connections being connected parallel to the capacitor. The line-side converter is coupled to an energy supply system. The DC voltage that is present at the capacitor is determined. A maximum voltage is predetermined. If the DC voltage present at the capacitor is determined to be greater than the maximum voltage, then at least two of the power semiconductor elements are switched into their conductive state in such a manner that the capacitor is discharged in the direction of the energy supply system.

Abstract: Power conversion apparatus for controllably converting alternating current (AC) to direct current (DC). An example apparatus includes multiple AC sources, galvanically isolated from one another, and multiple bridge rectifier circuits, including one or more controllable bridge rectifier circuits, where each bridge rectifier circuit has respective AC-side terminals and DC-side terminals and each bridge rectifier circuit is connected to a corresponding one of the AC sources via its AC-side terminals. The DC-side terminals are connected so that the outputs of the bridge rectifier circuits are combined in series. A control circuit is configured to individually control each controllable bridge rectifier circuit to selectively operate in a regulator mode, whereby a non-zero voltage less than or equal to the maximum rectifier voltage is provided, and a bypass mode, whereby the controllable bridge rectifier circuit provides a negligible voltage to its DC-side terminals and draws negligible current from its corresponding AC source.
