- the power generation unit 101 includes a lower electrode 101A provided on the elastic piece 102, a piezoelectric layer 101B made of a piezoelectric material such as PZT (lead zirconate titanate) provided on the lower electrode 101A, and the piezoelectric layer 101B.

A large amplitude is generated each time the elastic piece 102 is input, and the current i1 is generated while performing damped vibration. Further, since the external force is rarely constant, the amplitude at the time of input varies, and an unstable current i1 is output.
- the rectifier circuit 2 converts the AC output current i1 output from the power generation element 1 into a DC current, and outputs an output current i2L.
- the output current i2L is the sum of the charging current i3C flowing through the storage capacitor 3 and the current i6 flowing through the delay unit 6. At this time, since the DC / DC converter 4 is not activated, the current i4 does not flow.
- the storage capacitor 3 is charged with the current i3C, and when the DC / DC converter 4 is activated, the discharge current i3D is input to the DC / DC converter 4. Therefore, the voltage Vin input to the DC / DC converter 4 is equal to the charging voltage of the storage capacitor 3.

- the comparator 7A of the control unit 7 operates to output an operation signal Sc that activates the DC / DC converter 4 when the input voltage to the comparator 7A is higher than the reference voltage Vref.
- the reference voltage Vref is a predetermined constant voltage.
- the control unit 7 is not limited to the comparator 7A, and can be replaced with a circuit that sends a signal for starting the DC / DC converter 4 to the DC / DC converter 4. Moreover, the control part 7 can also be incorporated in a DC / DC converter.
- the DC / DC converter 4 may not be started until the storage capacitor 3 is charged with desired power. it can.
- the rectifier circuit 2 rectifies the current i1 and flows a charging current i3C through the storage capacitor 3 to charge the storage capacitor 3.
- the input voltage Vin of the DC / DC converter 4 equal to the voltage generated in the storage capacitor 3 rises from 0 (V) at time 0 (sec) as shown in FIG.

- the load 505 is supplied with the electric power charged in the storage capacitor 503, but charges the storage capacitor 503 only up to the voltage at which the DC / DC converter 504 is activated. I can't. Therefore, in order to increase the power supplied to the load 505, it is necessary to change the voltage at which the DC / DC converter 504 starts by using a large-capacity storage capacitor 503 or changing the design of the DC / DC converter 504. In addition, the environmental power generation device 500 is increased in size and cost.
- the DC / DC converter 504 can be activated if the DC voltage Vin input to the DC / DC converter 504 is small. Since the required boost voltage is higher than that, the voltage is insufficient to boost the voltage. Since the DC / DC converter 504 is activated, it cannot be charged to a boostable voltage, and the charging power of the storage capacitor 503 is output as it is without boosting the DC voltage Vout to a desired value.
- the voltage Vout required to operate the load 505 is about 3.4V.
- the starting voltage of the DC / DC converter 504 is 2V

- the voltage Vout is saturated at about 1V and may not reach the required voltage of 3.4V.
- the DC / DC converter 504 when the input power is unstable, the DC / DC converter 504 is activated at time t504 before the storage capacitor 503 is sufficiently charged. As a result, the electric power generated from the power generation element 501 cannot be sufficiently stored in the storage capacitor 503 and flows to the DC / DC converter 504 as it is. As a result, the storage capacitor 503 is not sufficiently charged, so that the input voltage Vin of the DC / DC converter equal to the voltage of the storage capacitor does not reach the voltage value that can be boosted, and the output voltage Vout does not reach the predetermined voltage. Output from the DC converter 504. Furthermore, power cannot be stored in the storage capacitor 503 until the desired power, so that power cannot be efficiently supplied to the load 505.
- the DC / DC converter 4 can be activated after the storage capacitor 3 is sufficiently charged by using the delay unit 6 and the control unit 7 even with unstable input power. Therefore, the DC / DC converter 4 can output the output voltage Vout having a predetermined voltage necessary for the operation of the load 5 and can supply sufficient output power.
- the current i6 is obtained from the current i1 generated by the power generation element 1, the current i6 is a kind of loss that is not included in the output of the energy harvesting apparatus 1001.
- the resistance value of the resistor 6A so as to increase to, for example, 500 k ⁇ or more, the value of the current i6 that causes loss can be reduced.

Therefore, the unstable attenuation input shown in FIG. 3 is intermittently generated. If the decay speed of the decay input is greater than the speed at which the delay capacitor 6B discharges and shuts down the DC / DC converter 4, the charge may not be sufficiently accumulated in the storage capacitor 3.
- FIG. 7 shows the input voltage Vin and the output voltage Vout of the DC / DC converter 4 of the energy harvesting apparatus 1001A.
- the discharge speed of the delay capacitor 6B can be controlled by the resistor 6C.
- the DC / DC converter 4 that is, the environmental power generation device 1001 ⁇ / b> A can intermittently supply power (output voltage Vout) to the load 5.

- the control unit 107 includes a CMOS inverter 107A that receives the voltage delayed by the delay unit 6 and outputs the operation signal Sc. Specifically, when the voltage Vin is applied and the voltage delayed by the delay unit 6 becomes higher than the threshold value of the CMOS inverter, the CMOS inverter 107A operates.
- the CMOS inverter 107A can be designed such that the threshold is set independently of the voltage input to the CMOS inverter 107A.
- the DC / DC converter 4 is activated until the storage capacitor 3 is charged with desired power, similarly to the energy harvesting apparatus 1001 according to the first embodiment shown in FIGS. 1 to 5.
