摘要：
In this paper we investigate an electrical circuit and its optimization for vibration energy harvesting using electromagnetic transducer. A step-up DC-DC converter regulated by Pulse-Width Modulation (PWM) is used to boost the voltage and control the power flow. An analytical expression for the optimal power flow from the rectified electromagnetic harvester is derived as a function of PWM duty cycle, vibration amplitude and frequency. Optimal duty cycles for both continuous and discontinuous modes are obtained analytically. The impedance of electromagnetic transducer and forward voltage drop of the diodes have been taken into account. It is also interesting to note that if a large inductor is adopted between the rectifier and step-up DC-DC converter, the energy harvesting system will exactly have the effect of Coulomb friction damper.
