| 摘要 |
The present invention relates to a method to generate at least a supply voltage to supply energy to a hearing device, whereas the ratio between the supply voltage and the source voltage is adjustable. The hearing device substantially comprises a source (Q), at least a switching element (S1, . . . , Sn), at least an energy transfer element (EUE), at least an energy storing element (ES), a load (Z) and a control unit (CTRL), whereas the method consists in that, in a first step, the control unit (CTRL) acts on the switching elements (S1, . . . , Sn), such that energy is transferred from the source (Q) to the energy transfer elements (EUE), that, in a second step, the control unit (CTRL) acts on the switching elements (S1, . . . , Sn), such that at least a part of the energy stored in the energy transfer elements (EUE) is transferred to the energy storing elements (ES) to build a supply voltage across the load (Z).
