Oscillation circuit for generating electrical energy from magnetic field has capacitance element provided by series capacitors with capacitance ratio determining output voltage

摘要

The oscillation circuit has a winding (1) acting as an inductive element and at least 2 series capacitors (3,4) acting as a capacitive element, one of the capacitors connected in parallel with a rectifier (5) providing the output voltage. The capacitance ratio of the capacitors is selected so that the required output voltage is obtained from the overall voltage of the oscillation circuit. A resonance capacitor (2) can be connected in parallel with the winding and the series capacitors acting as the capacitance element.
