Now to the maximal power tracing of solar battery 55, it is applied to above-mentioned DC voltage the embodiment of the invention also provides one kind and converts
The maximum power tracking method of device.
As shown in fig. 7, maximum power tracking method provided in an embodiment of the present invention, may include steps of：
Step 701, the input voltage and input current of period acquisition dc voltage changer.
In this step, the period acquires the input voltage and input current of dc voltage changer, refers between specified time
It is divided into the period, acquires the input voltage and input current of dc voltage changer.
Wherein, specified time interval can freely be set according to actual needs.For example, specified time interval can be set compared with
It is small, for example, being divided into 10 milliseconds (ms) or collection period between specified time is 10ms, to improve sensitivity；Specified time interval
Also can be set it is larger, for example, be divided between specified time 5 minutes or collection period be 5 minutes, to reduce calculation amount.
Step 702, input voltage and input current based on single acquisition, calculate the input work of dc voltage changer
Rate.
When it is implemented, input voltage and input current based on single acquisition, are equal to input voltage using input power
With the product of input current, the input power of dc voltage changer when calculating single acquisition.
Step 703, it according to the relationship of the current input power of dc voltage changer and an adjacent preceding input power, adjusts
The output voltage of dc voltage changer.
Due to the input power of dc voltage changer namely the output power of solar battery, according to direct current
The relationship of the current input power of pressure converter and an adjacent preceding input power, can determine solar battery present output power
Whether reach maximum, and then whether reach maximum according to solar battery present output power, adjusts dc voltage changer
Output voltage is so that the output power of solar battery is maximum.
Wherein, current input power is referred to and is calculated based on the last collected input voltage and input current
Input power, an and adjacent preceding input power refers to based on once collecting input voltage and input before the last
The input power that electric current is calculated.
When it is implemented, such load meets bearing power when charging so that load equipment is consumer electronics load as an example

The relationship of the output voltage of converter and the first given voltage threshold value, adjusts the output voltage of dc voltage changer.
Specifically, the condition of the first given voltage threshold value is greater than or equal in the output voltage of dc voltage changer
Under, show output voltage to reach load maximum voltage, the output power of dc voltage changer has reached the limit, at this time can not
Continue to improve output voltage, then keeps the output voltage of dc voltage changer constant.
Under conditions of the output voltage of dc voltage changer is less than the first given voltage threshold value, show output voltage also

In, other values can also be freely set as, are not used to specifically limit herein.
Under conditions of the current input power of dc voltage changer is less than or equal to an adjacent preceding input power, this
Kind of situation show solar battery not with maximum power output, the output voltage of the dc voltage changer of period acquisition at this time and defeated
Electric current out, output voltage and output electric current based on single acquisition, calculates the output power of dc voltage changer, in direct current
When pressure converter present output power is less than an adjacent preceding output power, according to the output voltage of dc voltage changer and the
The relationship of two given voltage threshold values, adjusts the output voltage of dc voltage changer.
Specifically, the condition of the second given voltage threshold value is less than or equal in the output voltage of dc voltage changer
Under, show that output voltage has been lowered to load minimum voltage, if continuing to reduce output voltage, can not charge to load equipment,
Then keep the output voltage of dc voltage changer constant.
Under conditions of the output voltage of dc voltage changer is greater than the second given voltage threshold value, show output voltage also
It can decline, then reduce the output voltage of dc voltage changer, to increase the output power of dc voltage changer, increase simultaneously
Add the output power of solar battery.
Wherein, the second given voltage threshold value can be set to load minimum voltage, then the second given voltage threshold value is less than the
One given voltage threshold value.Certainly, in other embodiments of the present invention, other values can also be freely set as, are not used to herein
It is specific to limit.
When specific implementation step 703, according to the current input power of dc voltage changer and an adjacent preceding input power
Relationship, adjust the output voltage of dc voltage changer, several situations as shown in Figure 8 can be summarized as.
Specifically, as shown in figure 8, current input power indicates that an adjacent preceding input power is indicated with Pk-1 with Pk,
Output voltage indicates that the first given voltage threshold value is indicated using Uo max using Uo, and the second given voltage threshold value uses Uo min
It indicates.According to the relationship of the current input power of dc voltage changer and an adjacent preceding input power, adjusts DC voltage and turn
The output voltage of parallel operation specifically includes following four situation：
Situation one is greater than an adjacent preceding input power in current input power, and output voltage is greater than or equal to first
Under conditions of given voltage threshold value, maximum voltage output is kept, namely keep output voltage constant；
Situation two is greater than an adjacent preceding input power in current input power, and output voltage is less than the first specified electricity
Under conditions of pressing threshold value, output voltage is improved；
Situation three is less than or equal to an adjacent preceding input power in current input power, and present output power is less than phase
Adjacent previous output power (not shown), and output voltage is less than or equal under conditions of the second given voltage threshold value, keeps
