Abstract:
A voltage and current triggered switch that turns on when a voltage across the switch reaches a turn-on voltage and that turns off when a current through the switch drops below a holding current. The switch features a Zener diode having a breakdown voltage. The Zener diode is connected to set the turn-on voltage of the switch to be the breakdown voltage of the Zener diode. Also provided is a step-down DC-DC converter comprising such a switch. Also provided is a system that has a tribo-electricity source or a piezo-electricity source, the provided step-down DC-DC converter and a load connected to an output of the stepdown DC-DC converter.

Claim (Index 19):
A method comprising:\n rectifying AC electricity from a tribo energy harvesting device or a piezo energy harvesting device; storing the rectified electricity in a first capacitor; once the voltage across the first capacitor has built up to a turn-on voltage set by the breakdown voltage of a Zener diode, closing a V&I triggered switch with turn-on voltage threshold set by Zener diode breakdown voltage (VITSZ) to transfer the energy stored in the first capacitor to an inductor; opening the VITSZ, triggered by a current dropping below a threshold current; transferring energy from current in the inductor to a voltage across a second capacitor; and a load consuming the energy stored in the second capacitor.
