Embodiment
Please refer to Fig. 3, the controller for solar of a kind of embodiment comprises the first switching tube Q1, storage battery and the second switch pipe Q2 that is coupled successively from the solar cell output, also comprises the second contact electric-controlled switch RLY2 that is connected in parallel with second switch pipe Q2.First and second switching tube Q1, Q2 are preferred but be not limited to adopt MOSFET, and the first switching tube Q1 preferably is connected in series by two MOSFET and forms.The second contact electric-controlled switch RLY2 is preferred but be not limited to adopt magnetic latching relay.Wherein, the second contact electric-controlled switch RLY2 is controlled keeps open-minded in battery tension is in normal range (NR) the time.
Output discharge loop to storage battery adopts switching tube and magnetic latching relay paralleling model, can guarantee when main control circuit damage or maintain and replace load equipment to be kept normal output state, so can not cause under the load because of there being control signal.Generally; output to load is opening state; only occurring under the under-voltage needs of storage battery electricity or storage battery overvoltage needs protection load and just needs to disconnect during electricity down; so according to present embodiment; the back battery tension is in normal range (NR) as long as power on; magnetic latching relay remains closed and promptly keeps this branch road open-minded, even when causing second switch pipe Q2 to turn-off in master board fault or maintenance, also can utilize the magnetic latching relay branch road to the load transmission of electric energy.
On the other hand, because magnetic latching relay contact good pressure-resistant performance, interference performances such as the anti-thunderbolt of output loop also improve greatly.Because controller for solar need be at the outdoor solar cell array that connects, natural calamity such as very easily be struck by lightning, according to traditional scheme, switching tube for example triode, MOSFET, IGBT etc. is subject to thunderbolt and damages, natural calamity abilities such as the anti-thunderbolt in contact electric-controlled switch contact are then much better than, thereby can strengthen the reliability of controller for solar.
Preferably, make that second switch pipe Q2 is controlled to be in opening state turning on and off of magnetic latching relay in the process, concrete control mode is as follows:
At battery tension just often, after the controller start, control second switch pipe Q2 is open-minded earlier, send drive signal by drive circuit of magnetic latching relay again and make the magnetic latching relay closure, because the second switch pipe Q2 in parallel with magnetic latching relay is in opening state, this moment, the magnetic latching relay closure was the no-voltage closure, and the life-span is not had harmful effect.After the magnetic latching relay closure, the magnetic latching relay drive signal disconnects, and magnetic latching relay is in closed hold mode, and can disconnect second switch pipe Q2 this moment, reduces turn-on consumption.
When battery tension is too high or too low, when other abnormality needs under the load electricity, make second switch pipe Q2 earlier open-minded, and then send drive signal by drive circuit of magnetic latching relay magnetic latching relay is disconnected, because the second switch pipe Q2 that is connected in parallel with magnetic latching relay is in opening state, this moment magnetic latching relay to disconnect being that no-voltage disconnects, the life-span is not had harmful effect.After magnetic latching relay disconnected, the magnetic latching relay drive signal disconnected, and magnetic latching relay is in the disconnection hold mode, disconnected second switch pipe Q2 switching tube this moment again, realized that load down.
Please refer to Fig. 4, in a kind of improved embodiment, controller for solar also comprises the first contact electric-controlled switch RLY1 that is connected in series with the first switching tube Q1.The first switching tube Q1 is preferred but be not limited to adopt single MOSFET.The first contact electric-controlled switch RLY1 is preferred but be not limited to adopt magnetic latching relay.
The input charge circuit switch of storage battery adopts the first switching tube Q1 and magnetic latching relay series model, is equivalent to irritate switch with the counnter attack that magnetic latching relay substitutes in traditional controller.Do not finish or polarity inverse time in the detection of input polarity, magnetic latching relay is failure to actuate, and keeps off-state.Because withstand voltage between the magnetic latching relay contact be several kilovolts, be that the controller for solar input of hundreds of volt does not have problems for the input ceiling voltage, can bear always.Before being the normal charging of storage battery, controller for solar carries out polarity according to the solar battery input voltage and judges, when the input error-polarity connection, controller for solar can provide alarm, the control magnetic latching relay keeps off-state, after, input correct until polarity was normal, magnetic latching relay was just controlled and closed, makes controller for solar enter normal charging state of a control.Prevent that with traditional withstand voltage pattern of employing switching tube anti-the scheme of filling is compared, the conduction loss of magnetic latching relay when operate as normal is lower than the switching tube conduction loss, thereby reduced the working loss of controller for solar.
Equally; natural calamities such as first switching tube also very easily is struck by lightning and damaging; and after in the storage battery input circuit, the magnetic latching relay that is connected in series with the first switching tube Q1 being set; because natural calamity abilities such as the anti-thunderbolt in magnetic latching relay contact are much better than; when the impaired short circuit of the first switching tube Q1 causes the storage battery overvoltage; magnetic latching relay can disconnect charge circuit, thereby effectively protects storage battery.
In preferred embodiment, the first switching tube Q1 does not initially have drive signal, be in off state, when controller for solar input polarity is correct, drive circuit by magnetic latching relay sends the closed drive signal of a magnetic latching relay, makes the magnetic latching relay action, transfers closure to by often opening, input magnetic keeps drive signal automatic disconnection after the magnetic latching relay closure, and magnetic latching relay is kept closed.Then, control the first switching tube Q1 and open and enter charged state, according to battery tension carry out the break-make management and to solar energy input carry out the square formation management.Because when magnetic latching relay was closed, the first switching tube Q1 did not have drive signal, is in off-state, so magnetic latching relay is the zero current closure when closed.Magnetic latching relay zero current closure more is better than exchanging charged break-make, and the life-span is longer, and general break-make number of times can reach more than 100,000 times.In the time of by day, controller for solar work, magnetic latching relay is kept closed always; Input pull-down voltage when being lower than battery tension up to the solar cell array in evening, the control first switching tube Q1 turn-offs earlier, drive circuit of magnetic latching relay sends the drive signal that magnetic latching relay disconnects again then, after making the magnetic latching relay disconnection, the drive signal of drive circuit of magnetic latching relay also disconnects, and after this magnetic latching relay keeps off-state.When daytime the square formation input voltage normal and when being higher than battery tension, storage battery input charge circuit just can reenter charged state.
As seen, adopt above-mentioned controller for solar, can make to load on that main control circuit damages or during no drive signal such as maintenance, load is kept normally exporting; Load simultaneously powers on or down during electricity, magnetic latching relay is a zero voltage switch, increases the service life.Can also reduce the influence of natural calamities such as thunderbolt.After further improving, can also simple realization import anti-reverse function, and input normal loss can not increase; Can prevent that the electronic device switch from because of damages such as thunderbolt can't disconnect, causing accumulator super-charge or damage; Simultaneously controller powers on, and the square formation input is opened or when disconnecting, magnetic latching relay is a Zero Current Switch, increases the service life.
In the above embodiments, switching tube also can be transformed to IGBT, triode etc. by MOSFET, and the also available non-magnetic latching relay of magnetic latching relay, magnetic latching contactor, non-magnetic latching contactor substitute.
In the above embodiments,, both can adopt the control model of long break-make type, also can adopt the control model of PWM type, all be suitable for above-mentioned scheme the control of switching tube.Just for the control model of long break-make type, switching tube is in the long period opening state, and is the square wave opening state of change in duty cycle under the control model of PWM type.
