CIRCUIT FOR A SYSTEM FOR CONTACTLESS, INDUCTIVE POWER TRANSMISSION |
摘要 |
The invention relates to a circuit for a system for contactless, inductive power transmission, in particular for use in supplying power to mobile devices, and to an associated charging circuit. The circuit comprises a primary-side circuit, which is disposed on a primary side and can be connected to a primary-side supply voltage, and a secondary-side circuit, which is disposed on a secondary side and can be connected to a load to be supplied with power. Furthermore a transformer stage having galvanic isolation is provided for the contactless transfer of power from the primary side over an air gap to the secondary side, wherein at least two magnetically coupled coils are provided for inductive power transmission and can be spatially separated from one another by distancing the secondary side from the primary side. The transformer stage has a resonant converter and the secondary-side circuit further comprises a restabilisation stage. |
