Lo scenario
A piezoelectric transducer outputs low AC voltage from vibrations; a voltage doubler rectifies and boosts it to charge a storage capacitor that powers a wireless sensor node.
Cosa contiene questo disegno
Leggi le decisioni che ne stanno alla base.
01
Use Schottky diodes for low forward voltage drop
02
Use voltage doubler topology to raise harvested voltage
03
Add large storage capacitor to smooth intermittent energy
Suitable for low-power IoT sensor nodes powered by vibration or mechanical stress where output voltage needs doubling and smoothing.
