    • The variable power transmission system for online electric vehicles of the present invention comprises: a power-source supply unit for supplying an alternating-current power source; a converter for converting the alternating-current power source supplied from the power-source supply unit into direct current; an inverter for converting the converted direct current from the converter into alternating-current power and transmitting the same to a power-receiving system; and a power-transmission control unit for judging whether power is being received by the power-receiving system, and for effecting variable control of the power transmitted to the power-receiving system from the inverter. The present invention has the advantageous effect that it can dramatically reduce power loss occurring in the inverter in a non-contact power transmission system for online electric vehicles, by reducing the transmission power of the inverter in situations where power is not being received in a secondary-side power receiving system by effecting variable control of primary-side inverter power transmission depending on whether or not power is being received in the secondary-side power receiving system.

    • The present invention relates to a power supply segment apparatus for an electric vehicle, in which magnetic field interferences between segments are minimized. More particularly, the present invention relates to a power supply segment apparatus for an electric vehicle, in which power-supplying segments are sequentially arranged along a travel direction under a road so as to supply power to the electric vehicle traveling on the road, wherein said apparatus comprises a shielding device mounted on an upper surface or at either end of a side surface of a segment-type structure so as to compensate for electromagnetic fields generated by both ends of power-supplying segments. According to the present invention, the amount of interfering magnetic fields which pass over to a neighbor segment is minimized, thereby satisfying various domestic and foreign EMI/EMC/EMF standards associated with electromagnetic waves, which each segment block should satisfy. Further, according to the present invention, the shielding device, which is capable of compensating for magnetic fields of various sizes and various types, can be contained in segment blocks in accordance with the conditions of the installation area, thereby enabling the mass production of various types of segment blocks, and thus reducing production costs.

    • The invention relates to an apparatus for shielding an electromagnetic field of a dual rail power supply system for an on-line electric vehicle, comprising: a power supply rail buried under a road and extending along the lengthwise direction of the road; a power supply core electrically insulated from the power supply rail and arranged beneath the power supply rail; a power-collecting device to which power is supplied from the power supply rail through electromagnetic induction; and shielding members arranged at either side of the power supply core so as to shield electromagnetic fields generated by the power supply rail and the power-collecting device. According to the present invention, a loop-shaped porous mesh made of SUS materials is buried underground up to a predetermined depth so as to reduce the intensity of electromagnetic fields generated by a power supply/collecting device of the on-line electric vehicle. Thus, electromagnetic fields are consumed, as current, by the loop-shaped porous mesh buried underground, even when the output from the power-collecting device increases, and therefore the level of electromagnetic fields satisfies the reference level 62.5mG, and the number of shielding plates attached to lower portions of conventional vehicles can be reduced.
    • 用于屏蔽在线电动车辆的双轨电源系统的电磁场的装置技术领域本发明涉及一种用于屏蔽在线电动车辆的双轨电源系统的电磁场的装置,该装置包括:埋设在道路上并且沿着道路的纵向方向延伸的电源轨道; 与供电轨电绝缘且设置在供电轨下方的供电核心; 电力收集装置,通过电磁感应从所述电力供应轨道向其供电; 以及布置在供电核心的任一侧处的屏蔽部件,以屏蔽由供电轨道和集电装置产生的电磁场。 根据本发明,由SUS材料制成的环形多孔网掩埋在预定深度的地下,以减小由在线电动车辆的供电/采集装置产生的电磁场的强度。 因此,即使当集电装置的输出增加时,电磁场作为电流被埋入地下的环形多孔网状物消耗,因此电磁场的水平满足参考水平62.5mG,并且数量 可以减少附接到常规车辆下部的屏蔽板。
