Contact-free energy transfer system from a primary conductor to a secondary development arranged on a vehicle

摘要

a contactless energy transfer system from a primary conductor, which can be charged with alternating current, by a stationary feeding unit to a secondary power transfer system (1) located on a vehicle (2);where the vehicle (1) is equipped with a voltage signal, the frequency of which is higher than the frequency of the alternating current, to transmit information;where a voltage induced by the voltage signal in a further winding is supplied to the feed-in unit to control the alternating current,where the feed-in unit has a means of detecting the level of output of an on-off voltage signal,where the feed-in unit has a means of charging the primary conductor with the alternating current for the transmission of electrical power, depending on the level of output,where the primary conductor is not charged with alternating current at the rate of extinction, and where the primary conductor is charged with alternating current at the full rate of extinction,where, in the case of an output level between the disappearing and full output, the primary conductor is charged only with alternating current for the transfer of power,where the information is transmitted by means of close field communication by inductive close field coupling,where the range of near field communication is less than half the width of a primary field plate, i.e. a ferrite plate covering the primary winding (3),where the ferrite plate is located on the side of the winding which is turned from the vehicle (1),where the information is transmitted in the form of a binary signal generated by the vehicle (1) and evaluated by the feed-in unit,where the information is coded as the output rate of an on-off voltage signal and as the pulse width modulation ratio of a pulse width modulated voltage signal,where the vehicle (1) has a state-of-the-art automatic control for generating the voltage signal,where the information contains an element indicating a conditional load or a conditional load requirement separately from a necessary, i.e. absolute, load or required, i.e. absolute, load requirement,where, in the case of a conditional charging requirement, the stationary charging unit activates the energy transmission depending on external influences;where the feed-in unit is fed from an electrical supply network, the supply voltage of which is generated from electrical energy generating installations;where, in the case of conditional alternating current contraction, the unit of supply in the primary alternating current is only significant if the total power produced by the installations exceeds a minimum value;where at least one of the installations uses a renewable energy source, namely a wind energy installation.
