Embodiment
Embodiment 1, and the present embodiment is that a kind of solar battery group, batteries and mains supply of adopting is as the electric supply installation of input power.
As shown in Figure 1: use in the receiving end of high frequency switch power power-supply device and control and change-over circuit between solar panel access point.It consists of alternating current input power supplying, solar battery group and detection circuit for access, MCU control circuit, battery management circuit and batteries, secondary side voltage transitions.
In the present embodiment, solve the electric power resource saving that outdoor power supply improves external utilization of new energy resources rate and outdoor power, reliable and stable equipment power supply is realized in the unsettled country of AC network and region.
During power connection normal operation, by 220V, exchange the adjustable alternating current input power supplying of input, access bus provides voltage, then powers to receiving end through secondary side voltage transitions, and battery management circuit accesses bus by batteries and carries out reporting of management of charging and discharging and battery pack data.
When solar panel photograph is subject to sunlight, solar battery group produce power access bus, and by battery detection circuit for access, the energy that reports real-time solar battery group to provide, according to testing result, report to MCU and compare calculating, adjust the voltage reference voltage of alternating current input power supplying as standard by MCU, it is flux matched that the voltage that in good time changes alternating current input power supplying access bus carries out energy, guaranteeing the reliable while of stable output, to reach solar battery group peak use rate.
Because solar battery group is when intensity of sunshine is different, the energy providing is different, and MCU circuit is by Intelligent Measurement adjustment, reliable to guarantee stable output.
When as low in intensity of sunshine, the energy providing is low, is not enough to supply with receiving end energy, and now, through adjusting, alternating current input power supplying also provides energy to bus by continuing, and guarantees the reliable and stable work of receiving end, but has also reduced the power consumption that exchanges input simultaneously.
If but solar battery group is when intensity of sunshine is high, the energy providing is high, not only can supply with receiving end completely by bus, can also start the battery management circuit storage that charges a battery.Now MCU also will compare after calculating according to the data that report, and by adjusting the reference voltage of alternating current input power supplying, makes alternating current input power supplying enter standby, further reduces the power consumption that exchanges input.And be also now ambient temperature higher time, power supply is not worked at this moment, has also reduced the required radiating condition requirement of power supply the useful life of not only high power supply.
And batteries has also been stored energy by solar cell, when MCU detects solar panel and there is no energy, and accessing bus by access automatically by battery management circuit, batteries powers.
In sum, when having the input of interchange, alternating current input power supplying access bus is that current collector is powered by secondary side voltage transitions again; Have after sunshine, solar panel access bus is current collector power supply and accumulators group charging storage, and turn-offs alternating current input power supplying saves energy.At night, MCU controls batteries, and access bus is powered to current collector.
The condition that this circuit can be used according to reality, can realize minimum input, because of being the single AC network that is not incorporated to, can be little in the early investment of solar battery group, and can realize the power supply of three kinds of modes, and guaranteed the stable of power supply and reliably.When interchange input stops, can switch to solar battery group power supply and batteries power supply.If solar battery group apolegamy is proper, can realize long-term nothing and exchange power consumption, reduced energy resource consumption.
As shown in Figure 2, civil power input power, by being connected to bus by MCU control circuit.And being connected by the first maximum tracking circuit MPPT1 and MCU control circuit, in MCU control circuit, by MCU internal program, write corresponding situation, export different PWM modulation signals and by U4, change the fiducial value of voltage feedback circuit, flux matched thereby the voltage that changes alternating current input power supplying access bus carries out energy.
Solar battery group connects bus by detection circuit for access, by the first diode, is connected to bus.And sun group voltage is connected to MCU control circuit pin by electric resistance partial pressure, by external components and parts, detect solar battery group electric current and be coupled to MCU control circuit pin by electric resistance partial pressure, report real-time voltage and current, with calculating with MCU internal program and comparing, measure solar battery group status and ceiling capacity output, control respectively corresponding operating state.As shown in Figures 2 and 3.
Fig. 4 is battery management circuit circuit and batteries, battery tension, electric current are connected to MCU control circuit by electric resistance partial pressure, report current battery condition, and according to after the comparison operation of MCU internal processes, from the 30 pin output pwm signals of MCU, be connected to the second maximal power tracing MPPT2, control battery charging.And when without solar battery group noenergy, via diode, be connected to bus and provide voltage for receiving end, and now, MPPT1 above and MPPT2 carry out standby by MCU control circuit output signal.
