illustratively, the magneto-electric module 10 may include a magnet and a coil, the magneto-electric module 10 generates the first power signal by the operation of the magnet and the coil, and the voltage switching module 20 compares the received first power signal with a preset voltage range. Specifically, if the first power signal is not included in the preset voltage range, the voltage switching module 20 may output a feedback adjustment signal to the magneto-electric module 10, and the magneto-electric module 10 adjusts the output first power signal according to the feedback adjustment signal.
for example, the faster the fan rotates, the larger the voltage value of the first power signal is, the overvoltage phenomenon occurs to the fan, the first power signal exceeds the preset voltage range, the voltage switching module 20 outputs the feedback adjustment signal to the magneto-electric module 10, and the magneto-electric module 10 can turn down according to the received feedback adjustment signal to output the first power signal; the slower the rotation speed of the fan is, the smaller the first power signal is, the under-voltage phenomenon occurs to the fan, the first power signal is lower than the preset voltage range, the voltage switching module 20 outputs the feedback adjusting signal to the magneto-electric module 10, the magneto-electric module 10 can amplify the feedback adjusting signal to output the first power signal, and the magneto-electric module 10 adjusts the output first power signal according to the feedback adjusting signal to enable the first power signal to be included in the preset voltage range.
In addition, if the first power signal is included in the preset voltage range, the voltage switching module 20 directly outputs the second power signal to the output adjustment module 30, where the second power signal is the first power signal, and the output adjustment module 30 adjusts the charging signal output to the fan load 40 according to the received second power signal and supplies the voltage of the second power signal to the fan load 40 through the output adjustment module 30. Therefore, the voltage value of the first power supply signal is compared with the preset voltage range by using the voltage switching module, so that the first power supply signal output by the magneto-electric module can be fed back in time to adjust when the first power supply signal is abnormal, and the power supply voltage in a safety range can be obtained no matter how the rotating speed of the fan changes.

Alternatively, the magnetic generating module 10 may include a plurality of coils connected in parallel, and the voltage switching module 20 is configured to switch the number of turns of the coil used for generating the first power signal in the magnetic generating module 10 according to the voltage value of the received first power signal and a preset voltage range. Specifically, the multi-path switching sub-module 23 automatically switches to the switch of the coil with the corresponding turn number according to the voltage adjusting signal output by the main control sub-module 22, so as to control the number of the coil which is operated in the magneto-electric module 10 and is used for generating the first power signal, and further adjust the first power signal output by the magneto-electric module 10.
