Maximum power output device of solar cell panel

Abstract

The invention relates to a maximum power output device of a solar cell panel. The maximum power output device comprises a BOOST circuit which is connected with the solar cell panel to provide the electric energy output by the solar cell panel for loading equipment and a power detection circuit which is used for collecting the working power of the loading equipment. The BOOST circuit and the power detection circuit are both connected with a control circuit. The control circuit can adjust the output power of the BOOST circuit. After the BOOST circuit increases the output power, and when it is detected that the working power of the loading equipment also rises by the power detection circuit, the control circuit continuously adjusts the output power of the BOOST circuit until the working power of the loading equipment is detected to be kept stable by the power detection circuit. The maximum power output device of the solar cell panel is compact in structure, capable of achieving the maximum power output of the solar cell panel, capable of greatly improving the utilization efficiency of the solar cell panel, capable of maximally achieving the purpose that the solar energy is utilized while the energy is generated, wide in application range, safe and reliable.

Description

technical field [0001] The invention relates to a maximum power output device, in particular to a maximum power output device of a solar panel, belonging to the technical field of photovoltaic power generation. Background technique [0002] As a new way of electric energy production, solar discharge shows a broad space for development due to its characteristics of no pollution, no noise and simple maintenance. However, in practical applications, due to the nonlinear characteristics of solar panel characteristics, and its output is affected by light intensity, ambient temperature and load, etc., under a certain light intensity and ambient temperature, solar cells can work at different output voltages. , but only at a certain output voltage value, the output power of the solar cell reaches the maximum value. At this time, the operating point of the solar cell reaches the highest point of the output power-output voltage curve, that is, the maximum power point (Maximum Power Poi...

Problems solved by technology

[0003] The solar panel provides energy as a power source. Due to its own characteristics, there are series and parallel resistors and the characteristics of the diode, and the load condition, its power output cannot be maximized.

Since solar energy belongs to the type of instant use, if it is not used, the energy will be lost in vain. If the equipment works at the rated voltage, its power is certain. If the solar power is greater than the rated consumption of the equipment, the equipment will not be able to use up the solar energy. cause waste
