DOUBLE-RECTIFIER FOR A MULTI-PHASE CONTACTLESS ENERGY TRANSMISSION SYSTEM

摘要

The invention relates to a secondary-side rectifier of an inductive n-phaseenergy transmission system with N greater than or equal to 3, the energytransmission system having in each phase (W, V, U) a resonant oscillatingcircuit, each with at least one inductor (L S) and at least one capacitor (CS), andthe secondary-side resonant oscillating circuits being magnetically coupleabletoprimary-side resonant oscillating circuits, with the secondary-side resonantoscillating circuits being star-connected or mesh-connected and beingconnectedto a rectifier via external conductors (L1 - L N), wherein the rectifier has aseriesconnection of N diodes (D1, D k,..., D N) with identical conductingdirections, with asmoothing capacitor (C gr) connected in parallel with the series connectionandthe output voltage (U A) of the rectifier being applied to the connectingpoints (A1,A2) of the smoothing capacitor (C gr), the external conductor (L k) beingconnectedto the anode of the diode (D k) for all k = 1 to N, the terminal (A1) beingconnected to the external conductor (L1) and the cathode of the Nth diode (DN)being connected to the connecting point (A2).
