Need to step up voltage from 1.2V to 5V in seebeck pelteir plate setup

  1. Jan 17, 2014 #1
    My project is that I want to USB fire charger. Its a device that you place on or near fire that will use the Seebeck effect of a pelteir plate to charge a USB device.

    So far I learned that i will only get 1.2 volts from a pelteir connected with a Schottky diode. USB ports need 5 V to charge any device.

    I looked online on ways to step up voltage and the thing i found is a charge pump. Is the only way to step up voltages from 1.2 V to 5 V. I also found this link that steps up a solar panel voltage to 5 V, could the panel be swapped with a pelteir plate. (http://www.talkingelectronics.com/projects/SolarLight/PowerSupply5vSolar.html)

    Thank you for your replies in advance.

    Welcome to the PF.

    Use a Boost DC-DC converter to step up your voltage:
