Maximal power tracing circuit is as shown in figure 4, carry out power comparison, groundwork process using the Perturbed algorithms that interlock
Are as follows: when photovoltaic module voltage is power P1 at U1, when reaching U2 (U2=U1+ Δ U) by increasing disturbance voltage Δ U, photovoltaic
Power is P2, determines perturbation direction using the relationship of P1 and P2.If P2 > P1, it can determine that voltage disturbance Δ U improves output
Power.Hence, it can be determined that the maximum power point Pm of photovoltaic module on the right of U2, need to continue equidirectional increase voltage disturbance Δ U.
When component voltage is U4, by increasing voltage disturbance amount Δ U, component voltage U5, at this time P5 < P4, therefore component can determine
Maximum power point Pm on the left side of U5, need to reduce voltage disturbance Δ U and change its adjust direction.According to above-mentioned principle, into
The maximum power point of component will be obtained by overregulating.
Physical circuit implementation is as follows:
1) [t0-t1): Vmppt_ref≤Low threshold, Set=0
Initial time t0, Vmppt_ref < Low threshold, Reset=1, at this timeDue to Vsa in reduction voltage circuit >=
Vbus, therefore MPPT controls signal high level, Vsa >=Vbus, Vmppt_ref rises rapidly at this time；
Due toM2 shutdown, it is 0 that C2, which keeps the voltage value of previous moment, and the output of comparator 2 is low, Set=0；
Q=0, M1 are open-minded, and capacitor C1 charges, and the output of comparator 1 is low；
When the t1 moment, Vmppt_ref=Low threshold.
2) [t1-t2): Vmppt_ref >=Low threshold, Set=0
T1 moment, Reset=0, Set=0, capacitor C1, C2 charging；Still continue to increase for 1, Vmppt_ref, Vsa
Continue to increase；
T2 moment, Vmppt_ref=high threshold.
3) [t2-t3): Vmppt_ref≤high threshold, voltage disturbance
The t2 moment, Vmppt_ref=high threshold, Set=1, Reset=0, Q=1,M1 shutdown, capacitor C1 are kept
The 0.97Vsa at t2 moment, for comparator 1, anode is the 0.97Vsa at t2 moment, negative terminal Vsa, and anode≤negative terminal is defeated
It is out 0；M2 keeps open-minded, and the output of comparator 2 is 0；
(t2-t3) period, Set=0, Reset=0, Q remain 1, due toVmppt_ref voltage value reduces, Vsa
Also it constantly reduces, i.e. the negative terminal voltage of comparator 1 constantly reduces；
The t3 moment, anode >=negative terminal, comparator 1 output be 1, Reset=1, Set=0,Q=0.
4) [t3-t4): current disturbing
At the t3 moment, M1 is open-minded, and the output of comparator 1 is that 0, Reset=0, M2 is turned off, and capacitor C2 is kept for the t3 moment
0.97Isa, for comparator 2, anode is the 0.97Isa at t3 moment, and negative terminal Isa, anode≤negative terminal, exporting is 0,
Set=0；
(t3-t4) period, Set=0, Reset=0,Remain the increase of 1, Vmppt_ref voltage value, Vsa is therewith not yet
It is disconnected to increase, know that Isa is constantly reduced by sun battle array characteristic curve, i.e. the negative terminal voltage of comparator 2 constantly reduces；
The t4 moment, anode >=negative terminal, comparator 2 output be 1, Set=1, Reset=0, Q=1,
5)[t4+∞)
Start the voltage disturbance of a new round after the t4 moment again, then current disturbing, repeatedly, the operating point of sun battle array is not
Disconnected to approach maximum power point, small range is shaken near maximum power point after staggeredly disturbing for several times.
