Folder rectifier for non-contact multi-phase energy transfer systems

摘要

Rectifier on the secondary side, which is connected to an inductive energy transfer system of n phases, in which n is greater than or equal to three and the energy transfer system has on each branch (W, V, U) a resonant oscillating circuit with respectively at least one inductance (Ls) and at least one capacitance (Cs), and the resonant oscillating circuits on the secondary side can be magnetically coupled with resonant oscillating circuits on the primary side, in which the resonant oscillating circuits on the secondary side they are connected in star or polygon and are in connection with a rectifier through external conductors (L1, ..., LK, ..., LN), characterized in that the converter has a series circuit of exactly n diodes (D1, Dk, ..., DN) with the same direction of passage, a flattening capacitor (Cgr) being connected in parallel to the series circuit and applying the output voltage (UA) of the rectifier at points d e junction (A1, A2) of the flattening capacitor (Cgr), the external conductor (Lk) being connected to the anode of the circuit (Dk) for each k = 1 to N, a first junction point (A1 being connected) ) of the flattening capacitor with the external conductor (L1) that is directly connected to the anode of a first diode (D1) and the cathode of the Nth diode (DN) being connected to another junction point (A2) of the capacitor flattening, all external conductors (L1, ..., LK, ..., LN) can optionally be short-circuited with each other by means of a switching device consisting of a single switching element (S).
