Abstract
The invention provides the charge control method of a kind of solaode, first the dutycycle of PWM is set, make DC DC changer at certain certain operation at frequencies, after waiting DC DC changer stably, gather a power, be designated asP 1 , then reduce the dutycycle of PWM, make the output voltage of solaode increase, after waiting DC DC changer working stability, gather a power, be designated asP 2 , at this moment compare watt level, ifP 2 >P 1 , illustrate that present operating point is positioned at the left side of maximum power point, direction finding maximum power point to the right, continue to reduce the dutycycle of PWM, ifP 2 <P 1 , illustrate that present operating point is positioned at the right side of maximum power point, direction finding maximum power point to the left, the dutycycle of PWM to be increased, make solaode output voltage reduce.The invention has the beneficial effects as follows: can preferably improve the charge efficiency of solaode.
Description
Technical field
The present invention relates to charge control method, particularly relate to the charge control method of a kind of solaode.
Background technology
Solaode is a complicated nonlinear system, and its output becomes along with the change of outside environment factor
Changing, therefore, the most preferably improving the charge efficiency of solaode is those skilled in the art's technical problems urgently to be resolved hurrily.
Summary of the invention
In order to solve the problems of the prior art, the invention provides the charge control method of a kind of solaode.
The invention provides the charge control method of a kind of solaode, first the dutycycle of PWM is set, makes DC-DC
Changer at certain certain operation at frequencies, etc. DC-DC converter stably after, gather a power, be designated asP 1 , then reduce
The dutycycle of PWM, makes the output voltage of solaode increase, and after DC-DC converter working stability, gathers a power,
It is designated asP 2 , at this moment compare watt level, ifP 2 >P 1 , illustrate that present operating point is positioned at the left side of maximum power point, side to the right
To finding maximum power point, continue to reduce the dutycycle of PWM, ifP 2 <P 1 , illustrate that present operating point is positioned at maximum power point
Right side, direction finding maximum power point to the left, the dutycycle of PWM to be increased, make solaode output voltage reduce.
The invention has the beneficial effects as follows: by such scheme, can preferably improve the charge efficiency of solaode.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of the charge control method of a kind of solaode of the present invention.
Detailed description of the invention
The present invention is further described for explanation and detailed description of the invention below in conjunction with the accompanying drawings.
Consider the output characteristic of solar cell, super-capacitor component charging is used maximal power tracing disturbance control algolithm
Following the tracks of maximum power of photovoltaic cell change, Fig. 1 is super-capacitor component charge control algorithm flow chart.
As it is shown in figure 1, the charge control method of a kind of solaode, first the dutycycle of PWM is set, makes DC-DC become
Parallel operation at certain certain operation at frequencies, etc. DC-DC converter stably after, gather a power, be designated asP 1 , then reduce
The dutycycle of PWM, makes the output voltage of solaode increase, and after DC-DC converter working stability, gathers a power,
It is designated asP 2 , at this moment compare watt level, ifP 2 >P 1 , illustrate that present operating point is positioned at the left side of maximum power point, side to the right
To finding maximum power point, continue to reduce the dutycycle of PWM, ifP 2 <P 1 , illustrate that present operating point is positioned at maximum power point
Right side, direction finding maximum power point to the left, the dutycycle of PWM to be increased, make solaode output voltage reduce.
By performing above control algolithm, it is maximum that basic guarantee super-capacitor component obtains power, can preferably improve solar-electricity
The charge efficiency in pond.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, it is also possible to make some simple deduction or replace, all should be considered as belonging to the present invention's
Protection domain.
