Description
Technical field
The present invention relates to solar airconditioning field, particularly to a kind of solar energy sky with charging, control and H bridge inversion
Adjusting system.
Background technology
Solar air-conditioner system is made up of parts such as solaode, controller, accumulator and transducer air conditionings.Existing
Solar air-conditioner system has following defects that controller Lighting Protection Measures is ineffective, affects security of system performance；Accumulator is many
Inevitably there is inconsistent situation in capacity and self discharge between individual cell batteries, affects the life of storage battery.
It addition, when occur continuous print several overcast and rainy time, the electric power of accumulator is not enough to maintain and is powered equipment work
Needing, this will affect the normal work of the equipment of being powered, and will solve this problem, can strengthen accumulator and solar panel
Capacity, the most unavoidably need to lay power line, can bring about a large amount of construction and great number cost, its cost can be significantly
Rise.It addition, electromagnetic interference also can affect solar air-conditioner system, when it uses, reliability is the highest.
Meanwhile, traditional solar control circuit uses the mode that accumulator single supply is powered, low-voltage disconnects.This side
Formula there will be an endless loop: if the supply voltage of accumulator is less than the setting voltage of break function, solar control circuit
Will disconnect, and solar control circuit oneself cannot recover automatically, reason is that solar control circuit is only in electric power storage
Cell voltage is sufficiently high when can work, and the luminous energy of output could be charged a battery by solar energy by solar control circuit,
Even if solar energy output has electricity after controller for solar disconnects, but battery tension is inadequate, and controller for solar low-voltage disconnects,
So this part electric energy cannot be charged to inside accumulator, owing to solar energy-electric energy cannot be charged to accumulator, such battery tension
Would not rise, controller for solar would not restart.
In the design of common H-bridge inverter circuit is applied, four brachium pontis use identical power switch pipe (to use IGBT
Pipe or metal-oxide-semiconductor), whether use the H-bridge inverter circuit of IGBT pipe composition, or the H-bridge inverter circuit of employing metal-oxide-semiconductor composition,
The most all there are some problems.The problem existed is as follows: when 1, using IGBT pipe, due to IGBT pipe conduction voltage drop
Nonlinear characteristic makes the conduction voltage drop of IGBT pipe can't dramatically increase along with the increase of conducting electric current, is operating at full capacity
Time, inversion conversion efficiency is higher；Conversely, as the nonlinear characteristic of IGBT pipe conduction voltage drop makes the conduction voltage drop of IGBT pipe also
Will not be substantially reduced along with the reduction of conducting electric current, in the light hours, inversion conversion efficiency is relatively low.On the other hand be by
Low in the switching frequency of IGBT pipe, the frequency characteristic of the H-bridge inverter circuit being therefore made up of IGBT pipe is undesirable.2, MOS is used
Guan Shi, frequency characteristic improves, but owing to the conduction voltage drop of metal-oxide-semiconductor is linear so that the conduction voltage drop of metal-oxide-semiconductor can be along with leading
Alive increase and dramatically increase, when operating at full capacity, inversion conversion efficiency is relatively low；Otherwise, the conduction voltage drop of metal-oxide-semiconductor is also
Can be substantially reduced along with the reduction of conducting electric current, in the light hours, inversion conversion efficiency is of a relatively high.3, inversion efficiency can be with
Prime DC source changed power and change.Using the H-bridge inverter circuit of IGBT pipe composition, inversion efficiency can be with prime DC source merit
The increase of rate and increase；Using the H-bridge inverter circuit of metal-oxide-semiconductor composition, inversion efficiency can be with the increase of prime DC source power
Reduce.In photovoltaic inversion device or wind power generation inverter, it is more prominent that the shortcoming of this circuit manifests.
