  • A Dual-Output Thermoelectric Energy Harvesting Interface with 86.6% Peak Efficiency at 30 μW and Total Control Power of 160 nW

    • A thermoelectric energy harvesting interface based on a single-inductor dual-output (SIDO) boost converter is presented. A system-level design methodology combined with ultra-low power circuit techniques reduce the power consumption and minimize the losses within the converter. Additionally, accurate zero-current switching (ZCS) and zero-voltage switching (ZVS) techniques are employed in the control circuit to ensure high conversion efficiency at μW input power levels. The proposed SIDO boost converter is implemented in a 0.18 μm CMOS process and can operate from input voltages as low as 15 mV. The measurement results show that the converter achieves a peak conversion efficiency of 86.6% at 30 μW input power.

  • An Adaptive FET Sizing Technique for HighEfficiency Thermoelectric Harvesters
  • 2016
  • Ingår i: 2016 IEEE International Conference on Electronics, Circuits and Systems (ICECS). - Monte Carlo : IEEE. - 9781509061136 ; , s. 504-507
  • Konferensbidrag (refereegranskat)abstract
    • A theoretical analysis of losses in low power thermoelectric harvester interfaces is used to find expressions for properly sizing the power transistors according to the input voltage level. These expressions are used to propose an adaptive FET sizing technique that tracks the input voltage level and automatically reconfigures the converter in order to improve its conversion efficiency. The performance of a low-power thermoelectric energy harvesting interface with and without the proposed technique is evaluated by circuit simulations under different input voltage/power conditions. The simulation results show that the proposed technique improves the conversion efficiency of the energy harvesting interface up to 12% at the lowest input voltage/power levels.
