FIG. 5 shows the frequency characteristics of a power generation coil with a coil resistance of 5,000,5500 turns and a charger coil with a coil resistance of 80,100 turns. Here, the current flowing through the coil 5 is F = -z (F2: power supply voltage, z: coil impedance), and the magnetic flux Φ generated from this is L = NΦ (L: coil inductance, N: coil impedance). Volume a)
According to the relationship between shi, L and engineering L-, Φ-N "N-Z. The charging current 1 flowing through the power generation coil 5 due to this magnetic flux Φ increases the induced voltage of this coil e!
Then, it becomes eI-2πfNΦ (f: inductance of the alternating magnetic flux coil 5, voltage drop of the 71 circuit). Here, the charging current with respect to the alternating magnetic field frequency has a peak around 500 Hz, and as the frequency further increases, the charging current decreases. That is, since the frequency characteristics can be determined by the combination of specifications of the charger coil 5 and the power generation coil 5, equipment such as a frequency converter can be omitted by setting the frequency of the external power supply 40 near the commercial frequency band. Therefore, it is possible to reduce the cost of the charger, and by keeping the watch in a reset state during charging, resonance rotation of the watch rotor (not shown) can be prevented. In addition, if the high frequency band is set to avoid resonance rotation of the watch rotor, there is no need to reset the watch when charging, and the charger coil can be made smaller and lighter. be.

FIG. 4 shows the change in power supply voltage over time with respect to charging time. This characteristic not only increases the main frequency and power supply voltage of the external power supply 4, but also increases the magnetic flux generated in the gap of the core 2, which makes the slope of the magnetic flux dog-like, and the increase in the power supply voltage with respect to the charging time is accelerated.
