Description
Technical field
The utility model belongs to inverter technology field, more particularly to a kind of anti-PID effects DC-to-AC converter of intelligence.
Background technology
At present, because world energy sources crisis and environmental pollution are serious, current energy scarcity is can solve the problem that simultaneously finding one kind
The novel energy that can be used for a long time, and it is the sustainable renewable sources of energy so there was only wind energy and solar energy, and be cleanliness without any pollution, energy
The characteristics of source is enriched.Therefore in order to the earth environmental protection and people's energy demand satisfaction, start both at home and abroad it is popular in
Solar power generation power plant construction, still, the whole world are built in various large-scale, small-sized photovoltaic power stations, it was found that one is badly in need of urgent solution
Certainly the problem of, especially for by solar cell, find a serious PID effect in the power station of large area all be present, by
It is alternating current to be delivered to inverter to carry out inversion in generating on daytime in the photovoltaic module of photovoltaic plant, and supply load uses, still,
In the process, can accumulate gradually electric charge between photovoltaic component encapsulating material and film, and the electric charge of accumulation is more and more, just be formed
Ionosphere, the conversion efficiency of photovoltaic cell will be influenceed, so as to reduce photovoltaic module power, will be occurred not under serious situation
The electrical phenomena of generating.
The content of the invention
The utility model provides a kind of intelligence anti-PID effects inverter to solve technical problem present in known technology
Device.
The utility model is adopted the technical scheme that a kind of intelligence is prevented to solve technical problem present in known technology
