发明名称 Hearing aid device
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). <IMAGE>
