    摘要： A system includes a transformer (102) having a multi-phase AC input (104) and AC phase segment outputs (106, 108, 110). A plurality of rectifiers (112, 114, 116) are each connected to receive AC input from a respective one of the AC phase segment outputs (106, 108, 110). Each rectifier (112, 114, 116) has a respective positive DC output and a respective negative DC output. A first interphase transformer (IPT) (130) with a respective winding (132, 134, 136) is connected to each of the positive DC outputs of the plurality of rectifiers (112, 114, 116). The windings of the first IPT (130) are connected to an output node (138) of a positive DC power rail (140). A second IPT (142) with a respective winding (144, 146, 148) is connected to each of the negative DC outputs of the plurality of rectifiers (112, 114, 116). The windings of the second IPT (142) are connected to an output node (150) of a negative DC power rail (152). A power switch (154) is operatively connected from the positive DC power rail (140) to the negative DC power rail (152).

    摘要： An AC-to-DC (AC/DC) voltage multiplier of the present invention is constructed with at least one fundamental multiplier unit. Multiple fundamental multiplier units can be connected in a layered way to build up a multi-layer multiplier that multiplies the input voltage in a fast growth rate with increasing layers. Multiple multiplier units may also be connected in parallel to form multiple phase system with any arbitrary number of phases as desired. Comparing to the conventional approaches, this AC/DC voltage multiplier provides higher growth rate of voltage gain by increasing layers of multiplier units, while the current is more evenly distributed across the circuit from AC source to DC output. Furthermore, the topology is simple, which provides high design flexibility for multi-layer and multi-phase multiplier. The AC/DC voltage multipliers of the present invention are highly favorable for high-power and fast-charging applications to meet the market demand nowadays.

    摘要： An electric vehicle charging system according to an aspect of the present invention may comprise a transformer, an alternating current/direct current (AC/DC) converting system, a requested power operation unit, and an electric wire network in a parking lot, and may convert AC power to DC power so as to provide charging power to an electric vehicle, with less loss of power compared to that of the AC power, via the electric wire network in the parking lot. In addition, it is possible to install one or more of the transformer, the AC/DC converting system, and the requested power operation unit in a space, which is separated from a charging adapter (5015) of a parking area, and to provide a parking space having a larger number of charging adapters (5015) than the number of DC/DC converters.
