The invention relates to a method for accumulating the energy supplied by a piezo element (1), using a capacitor (6), whose terminals are electrically connected to the electrodes of the piezo element. Said method is characterised by the following steps: a) Generation of the piezo impulse and charging of a coil (4); b) After the coil has been completely charged transformation of the current stored in the coil in a capacitor (6) that is connected in parallel to said coil. The invention also relates to a device (circuit) for accumulating the energy supplied by a piezo element (1), using a capacitor (6), whose terminals are electrically connected to the electrodes of the piezo element. Said device is characterised in that a coil (4) is connected in parallel between the piezo element and the capacitor, whereby a diode (5) is connected in series between the coil and the capacitor, in such a way that the impulse generated by the piezo element does not reach the capacitor. |
