通过电阻阻抗控制实现感应式振动发电机谐振频率调制

Resonant frequency modulation is indispensable for vibration power generators using inductive coils to maintain maximum power extraction against environmental fluctuation. We have shown that by inserting a fixed reactance element in series with an inductive vibration power generator, its resonant frequency can be modulated only by controlling the resistive impedance of the power extraction circuit...
