The output voltage or load current of the micro motor will change the DC voltage of the rectifier filter output, which is not allowed for the micro motor system, so the voltage stabilizer circuit should be used to stabilize the load voltage. since most digital electronics require a stable dc voltage, the energy storage capacitor can not supply power directly to the load circuit. Only by converting the electricity collected in the capacitor into a stable DC, the output of the voltage stabilizer module can be sent to the target system to wake up the target system to work; on the other hand, the power consumption requirement of the power management circuit itself is extremely low, which can improve the power efficiency of the generator. based on the above considerations, the DC /DC voltage converter is used to connect the energy storage device and the load circuit to adjust the dc voltage to the stability value required by the wireless sensor node. When the voltage of the energy storage capacitor changes dynamically, the circuit can still provide stable power to each load.
