Abstract

The present application relates to an energy harvesting conditioning system. The above energy harvesting and conditioning system includes an energy storage circuit, a comparison circuit and a switch circuit. The input end of the comparison circuit is connected with the output end of the energy storage circuit. The controlled end of the switch circuit is connected to the output end of the comparison circuit. The potential terminal of the switch circuit is connected to the input terminal of the energy storage circuit. The comparison circuit controls the operation state of the switch circuit according to the value of the output voltage of the energy storage circuit, and further controls the operation state of the energy storage circuit. The energy harvesting and conditioning system provided by the present application utilizes the voltage of the energy storage circuit itself as the input voltage of the comparison circuit, and no external power supply is required, thereby reducing the complexity of the circuit.

Description

technical field [0001] The present application relates to the field of circuit control, and in particular, to an energy harvesting and conditioning system. Background technique [0002] With the continuous consumption of petrochemical energy and the increasingly serious environmental pollution problems, the demand for clean and renewable new energy is increasing. Solar energy has become a hotspot in new energy research due to its wide distribution, easy access, cleanliness, high efficiency, and sustainability. [0003] Due to the shortcomings of solar energy with strong output intermittent, greatly affected by external environmental factors, and not suitable for indoor use, it is difficult to ensure the reliability of sensor power supply by using this power supply method alone. Therefore, direct solar power supply can be used in conjunction with energy storage elements. That is, the energy in the solar cell is collected into the energy storage element to supply power to th...
