The 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.
What is in this drawing
Read the decisions behind it.
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.
