One, introductive

Smooth hot season is optimized implement, MPPT of illustrious name abbreviation, say Guang Fugong rate is optimized again implement optimize with package power implement, it is equipment of a kind of intelligence, aim to increase the energy efficiency of component of smooth hot season and stability.

Smooth hot season optimizes implement (the action of MPPT) :

Smooth hot season is optimized implement in be being used at the package that series connection of component of many smooth hot season fashions to string together, use real time to track single block component most high-power dot. The problem that the electricenergy production of system of smooth hot season that will because shadow keep out, component faces towards abhorrent place causes difference or package attenuation,be solved reduces.

Smooth hot season optimizes implement (the principle of MPPT) :

Join of component of every smooth hot season is had most high-power dot dogs of the function optimize implement, and the output of volt component receives every light to come optimize implement the input end of module. Optimize implement the electric energy that monitoring optimizes cell panel of every smooth hot season, although array is medium aleatoric a cell panel appears break when compounding a problem, other cell panel still can be outputted most high-power, because break the electricenergy production loss that compound a problem and produces,can compensate consequently.

Smooth hot season optimizes implement (the value of MPPT) :

1, raised package shady bring about electricenergy production to reduce a problem;

2, falling without shady circumstance use optimize implement, can increase the electricenergy production of about 1% ;

3, those who solve component of smooth hot season is comfortable compound a situation, can raise the package of about 2% comfortable match a loss, increase electricenergy production thereby;

4, optimize implement can detect the parameter of component of every smooth hot season, problem of can exact location is nodded, reduce carry dimension cost.

 

2, representative application develop attacks graph

 

3, representative application and type selecting are recommended

Smooth hot season is optimized implement (MPPT) uses circuit of step up of blame segregation DC-DC, the switch frequency of the MOS in DC-DC application is as high as hundreds of KHz, taller to the dynamic parameter requirement of MOS. Optimize in the light of smooth hot season implement DC-DC circuit, recommend use luck dark series of MOS-SGT of semiconductor low pressure. Extremely low guide electrify block, small loss, tall avalanche is able to bear or endure quantity, efficient, suit high frequency applying very much, enclose for DFN5*6.
