INSULATION MONITORING SYSTEM FOR SERIES-COMPENSATED WINDINGS OF A CONTACTLESS ENERGY TRANSMISSION SYSTEM

摘要

A device for contactless energy transmission may include series resonant circuits on primary and secondary winding sides, which may each include at least one coil and at least two capacitors. The series resonant circuit on the primary winding side may be connected to an upstream circuit, and the series resonant circuit on the secondary side may be connected to a downstream circuit. One or both coils may be coupled to fault-recognition resistors.
