研究成果概要

Triboelectric nanogenerator (TENG) is a new energy technology proposed in recent years. Full-wave rectifier (FWR) and half-wave rectification (HWR) are commonly used energy extraction circuits for TENG, so it's necessary to analyze the output characteristics of TENG under the condition of them.

  The calculation expression of the maximum output and optimal load of FWR and HWR for TENG is proposed in this research, which can help directly obtain the output characteristic without simulation or measurement. From the results, we can get that, unlike other energy harvesting devices, the output of HWR is higher than that of FWR for TENG, but the former requires the optimal load with larger resistance. And the results show that the output power of TENG is a linear function of frequency, and the optimal load is inversely proportional to frequency, which is consistent with the convention. It is worth mentioning that these optimal loads are equal to the internal equivalent resistance of TENG under the condition of FWR and HWR, so the output power of TENG with any loads can be easily gotten by using the voltage divider formula.

The calculation results are consistent with the simulation results by LTspice, which can prove the correctness of the calculation formula we proposed.
