Electrical power generation device and generation method

Abstract

The invention provides a device (and method) for generating electrical power, comprising an electrical power generator configured to generate an electrical output current using charge induction. A load capacitor is used for storing charge in response to the rectified electrical output current, wherein the load capacitor has a capacitance which increases with voltage. This means the voltage stored on the load capacitor becomes flatter as it is charged and discharged; in a relatively discharged state, the capacitance is reduced giving a relatively larger voltage based on the stored charge, and in a relatively charged state, the capacitance is increased giving a relatively smaller voltage based on the stored charge. This improves initial energy transfer from the generator towards the storage element (non-linear capacitor) and makes the output voltage more flat and easier for practical use.
