PROBLEM TO BE SOLVED: To provide a power supply arrangement having a wirelessly coupled control which avoids magnetic interactions that are encountered, when the operation of an inductively coupled switched-mode power supply is to be controlled by a control signal that hops wirelessly over a fixed distance on its way.;SOLUTION: This power supply system comprises a primary-side circuit and a secondary-side circuit, a power transformer 204, primary-side switching means 203, an inductively-coupled feedback link, secondary-side feedback pulse generating means, and primary-side means 209, 202 for utilizing feedback pulses in controlling the rate, at which energy is transferred from the primary side to the secondary side. In the power supply system, the generating means 206 are arranged, so as to generate the feedback pulse at a frequency, that is different from a self-excited oscillation resonance frequency of the switching means 203 at the primary side to repeatedly switch an electric current coupled to the power transformer 204.;COPYRIGHT: (C)2002,JPO
