Patent DE 10 2015 119 969
Arrangement for operating and/or measuring the generating power of a capacitive energy harvester
An arrangement for measuring the generating power of a capacitive energy harvester, comprising the following elements:
- a capacitive harvester capacitor (Cvar), the first and second electrodes of which are movable relative to each other in order to cause a change in capacitance when an excitation movement occurs;
- a storage capacitor (Cres), the second electrode of which is connected to the second electrode of the harvester capacitor (Cvar);
- a first diode (D1) whose anode is connected to the first electrode of the storage capacitor (Cres) and whose cathode is connected to the first electrode of the harvester capacitor (Cvar);
- a second diode (D2), the anode of which is connected to the first electrode of the harvester capacitor (Cvar);
- a voltage measuring device connected between the cathode of the second diode (D2) and the anode of the first diode (D1); and
- a charging capacitor (Cstore) connected between the cathode of the second diode (D2) and the anode of the first diode (D1).
