| 摘要 |
The invention relates to a method and device for non-contact energy transmission from one or several medium frequency current sources (21, 31, 61, 71), the mean frequencies of which may have deviations of fM, to one or several moving users, by means of one or several transmission lines and transmission heads provided for the moving user, with one or several matching regulators in series, for regulating the power drawn form the transmission line. The transmission lines are fed by the medium frequency current source with currents which are constant with regard to the effective value thereof. The currents fed to a matching regulator are each rectified in a rectifier (22, 32, 62, 72), smoothed with a link-circuit choke (23, 33, 63, 73) and combined, whereby said intermediate circuit current is either fed to the link circuit capacitor (27, 67), buffering the output voltage of the matching regulator, or drawn off said link circuit capacitor, according to the power requirements of the user connected to the matching regulator, by means of a single switch (5). The switching frequency of said switch is selected with a fixed value from within a tolerance band with a 10 % spread about 1/ fM and the output voltages from several matching regulators may be connected in parallel to supply a user, by means of diodes (51, 52). |
