Description
Technical field
The utility model relates to a kind of solar energy cloudy day energy-conservation power supply circuits, belongs to solar powered field, is applied to solar powered field.
Background technology
Known solar power supply circuit. after obtaining solar energy, pass through voltage conversion circuit, to system power supply. voltage transformation module is in work simultaneously, certain energy can be consumed, when the light such as cloudy day are more weak, the larger proportion just accounting for solar cell power generation of the energy of operational module consumption, even all can consume light the energy that solar panel produces. and make solar panel in low light level state, reduce and maybe can not provide the energy for system.
Summary of the invention
In order to overcome above-mentioned defect, the utility model object is to provide a kind of solar energy cloudy day energy-conservation power supply circuits, cloudy day or the low light level environment under, first get up by the electric current collection that solar energy is produced. when reaching a certain amount of, just allow voltage transformation module work. allow voltage transformation module interval work like this. reach the object reducing power consumption.When making the low light level, solar panel also can continue to provide energy.
To achieve these goals, the utility model adopts following technical scheme:
A kind of solar energy cloudy day energy-conservation power supply circuits, it comprises solar cell, electric capacity, voltage detection module, switch module;
Solar cell is connected with electric capacity, and electric capacity is connected with voltage transformation module by switch module;
Voltage detection module is connected with electric capacity and switch module respectively;
Electric capacity collects the electric current that solar cell provides;
Whether worked by voltage detection module control voltage modular converter;
Solar panel receives light, and generation current is to capacitor charging, and after capacitance energy storage, the voltage at electric capacity two ends raises gradually, and after electric capacity both end voltage rises to certain value, voltage detection module is started working, and opens switch module to voltage transformation module work;
Voltage transformation module, by the voltage of the power conversion on electric capacity needed for system, uses for system works and battery charging.
The beneficial effects of the utility model:
The utility model is first got up the collection of energy that solar panel produces by electric capacity, after capacitance voltage rises to certain value, enable voltage modular converter, by the energy of the storage of electric capacity, conversion is to system power supply. by controlling the operation range of supply module, reduce the power consumption of modular converter. and when making the low light level, solar panel also can continue to provide energy; Make solar energy weak at light, under the state that the electric current that can provide is little. improve the efficiency of power supply circuits. make solar cell also can provide the energy for system under low light level state; Make solar energy weak at light, under the state that the electric current that can provide is little, improve the efficiency of power supply circuits, make solar cell also can provide the energy for system under low light level state.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model;
Fig. 2 is that circuit of the present utility model illustrates figure.
Embodiment
Be described in detail below in conjunction with accompanying drawing 1,2 pairs of the utility model:
A kind of solar energy cloudy day energy-conservation power supply circuits, it comprises solar cell 1.1, electric capacity 1.2, voltage detection module 1.3, switch module 1.4;
