用于高压直流输电线路自供电传感器的谐波磁场能量收集

Due to the lack of abundant alternating electric and magnetic fields, there is no efficient and stable energy harvesting method for high-voltage direct current (HVDC) transmission lines, which hinders the deployment of self-powered sensors. The finite switching frequency of electronic devices results in the coexistence of dc and harmonic currents in HVDC transmission lines. In this article, a nove...
