全自供电电磁振动能量收集系统中的双时间尺度扰动观察法自动阻抗匹配

Most of electromagnetic vibration energy harvester (EVEH) systems are only focused on resistance matching at resonant frequency. However, the EVEH will have complex output impedance at nonresonant frequencies. Pure resistance matching cannot fully extract the maximum power at nonresonance. This article is the first to propose an automatic and fully self-powered complex impedance matching EVEH syst...
