This paper presents an integrated vibration power generator system. The system consists of a
mini electromagnetic vibration power generator and a highly efficient energy harvesting circuit
implemented on a minute PCB and a 0.35 μm CMOS integrated chip. By introducing a feedback control
into the DC-DC PWM Boost Converter with feedforward control, the energy harvesting circuit can adjust
the duty ratio of the converter following the variation of the input voltage and the voltage of energy storage
element to get high energy conversion efficiency. The energy harvesting circuit rectifies the input AC
voltage, step up the DC output of the rectifier by the DC-DC PWM Boost Converter with feedforward and
feedback control and store the electric energy into a super capacitor, which can be used as a small electrical
power supply for an intelligent micro sensor network. |
