Abstract
The invention provides a solar power generation type voltage conversion device, wherein the output power of a solar battery can be simply judged and resultant defects can be avoided. The transistor of a voltage conversion circuit is turned on, so that the current is enabled to flow through a coil into current detection resistor. Therefore, the power generation amount PM is metered. When the power generation amount PM is judged to be larger than a threshold value PMTH, the output power of the solar battery is judged to be supplied to a load. During the metering process of the power generation amount PM, the current is driven to flow through the coil. In this way, when the current is cut off through turning off the transistor, the transistor is turned on at the same time to prevent the generation of an excessively large counter electromotive force. Whine the power generation amount PM is judged to be smaller than the threshold value PMTH, the output power of the solar battery is not judged to be supplied to the load. The power supply is enabled or not is judged again after a re-judgment prohibition period TINT from the above time point.

MPPT controller 12 carries out the on-off of transistor Q1～Q4 and controls.Connecting transistor Q1,
Under the state disconnecting transistor Q2, by transistor Q3 and Q4 is carried out on-off conversion,
Thus carry out boost action, on the other hand, connecting transistor Q3, disconnecting the shape of transistor Q4
Under state, by transistor Q1 and Q2 being carried out on-off conversion, thus carry out blood pressure lowering action.
The adjustment of the output voltage VCO of voltage conversion circuit 11 carries out on-off conversion by change
The on-off dutycycle of transistor is carried out.
The other end of relay 14 is connected with accumulator 15, inverter 16 and auxiliary equipment 18.
The on-off of relay 14 controls to be carried out by vehicle control device 10.That is, could sentence in power supply
In fixed process, when being judged to supply possible, connect relay 14, on the other hand, when being judged to
Supply can not time, maintain off-state.
Fig. 3 and Fig. 4 is for illustrating that power supply could the time diagram of summary of determination processing.Figure
3 represent be judged to the example that power supply is possible, Fig. 4 represent be judged to power supply can not example.
In the present embodiment, when being disconnected relay 14, MPPT controller 12 is led to
Cross and transistor Q2 and Q3 is maintained off-state, and connect transistor Q1 and Q4, from
And measure the generated energy PM of solaode 2.That is, MPPT controller 12 is by connecting crystal
Pipe Q1 and Q4 measures the output electric current ISO flowing through resistance R1, and measures solaode
The output voltage VSO of 2, is applied to lower note formula (1) by output voltage VSO and output electric current ISO,
Calculate generated energy PM.Output electric current ISO is the both end voltage by gage resistance R1 and obtains
's.
PM=VSO × ISO (1)
It addition, in Fig. 3 and Fig. 4, illustrate in the downside of generated energy PM and flow through coil L1's
Coil current IL rather than output electric current ISO.Coil current IL is in the on-state of transistor Q1
Under, identical with output electric current ISO, gradually decrease after the disconnection of transistor Q1.
Power supply could the start time t0 of determination processing, disconnect transistor Q2 and Q3
State under, transistor Q1 and Q4 is connected together, by the output voltage VSO that measured with
And output electric current ISO is applied to formula (1) and calculates generated energy PM.
In the example shown in Fig. 3, generated energy PM continues increase and reach decision threshold at moment t1
Value PMTH (such as 15W).Therefore, it is determined that possible for power supply, transistor Q1 is disconnected
While connect transistor Q2.By connecting transistor Q2, it is possible to prevent because disconnecting transistor
Q1 and the excessive counter electromotive force that causes, it is possible to avoid due to excessive voltage to coil L1
Other components (particularly Q1, Q2) connected have undesirable effect.It addition, in this enforcement
In mode, the input side at voltage conversion circuit 11 measures generated energy PM.Therefore, with at voltage
The outlet side metering generated energy of translation circuit 11 also carries out the situation of Voltage Cortrol to maximum power point
Compare, it is determined that threshold value PMTH is set to smaller value.
Coil current IL increases, in the moment in the period of moment t0 to t1 in the same manner as generated energy PM
T1 gradually decreases later." 0 " is essentially become (from moment t1 when standby at coil current IL
Between TWAIT1) moment t2, connect relay 14 and start common MPPT maximum power point tracking
Control (MPPT control).That is, MPPT controller 12 connects transistor Q1, disconnects transistor
Q2, and transistor Q3, Q4 are begun to turn on disconnection conversion, defeated by voltage conversion circuit 11
Go out voltage VCO to control as magnitude of voltage maximum for generated energy PM.
In the example shown in Figure 4, although generated energy PM increases initially, but not up to judge
Threshold value PMTH is just saturated.In this case, if from the sart point in time of determination processing through limit
Time TPM processed, then be judged to power supply can not, at moment t3, disconnect transistor Q1's
It is also turned on transistor Q2.By connecting transistor Q2 in the same manner as the example shown in Fig. 3, it is possible to
Prevent the excessive counter electromotive force (example than Fig. 3 is little) caused because disconnecting transistor Q1,
It can be avoided that other components being connected with coil L1 are brought bad shadow due to excessive voltage
Ring.Afterwards, " 0 " is become afterwards (through stand-by time TWAIT2 from moment t3) at coil current IL
Moment t4 disconnect transistor Q2 and Q4.
Even if the most again carrying out power supply could judge, again carry out undecidable possibility
Property the highest, so have passed through from moment t3 fixing judge again to forbid period TINT time
Carve t5 to start to judge again.Until being judged to that power supply is possible, all repeating and judging again.
As above, in the present embodiment, by being temporarily switched on the crystalline substance of change in voltage circuit 11
Body pipe Q1 and Q4, thus one side makes current flow through resistance R1 one side metering generated energy PM, enters
Row this generated energy PM whether reach decision threshold PMTH power supply could judgement.
Fig. 5 be above-mentioned power supply could the flow chart of determination processing, reason vehicle control device at this
10 perform.It addition, in an initial condition, relay 14 is disconnected.
In step s 11, instruction MPPT controller 12 by connect above-mentioned transistor Q1 and
Q4 carries out the metering of generated energy PM, obtains generated energy PM.In step s 12, it determines send out
Whether electricity PM is more than decision threshold PMTH.Initially this answer is negative (NO), enters
Step S13 discriminates whether to light from the time started processed to have passed through restriction time TPM.Due to
Just this answer is also for negating (NO), so returning to step S11.
Before the answer in step S13 becomes affirmative (YES), the answer of step S12 becomes willing
Time fixed (YES), it is determined that possible for power supply, while disconnecting transistor Q1, connect crystal
Pipe Q2 (step S14).Then, standby to through setting the most in advance with decision threshold PMTH
Till fixed stand-by time TWAIT1 (step S15), in stand-by time TWAIT1 through laggard
Entering step S16 and connect relay 14, instruction MPPT controller 12 starts common MPPT control
System.
On the other hand, returning of affirmative (YES) step S13 before is become when the answer in step S12
Answer become certainly (YES) time, it is determined that for power supply can not, disconnect the same of transistor Q1
Time connect transistor Q2, the value judging time timer T again is set as " 0 " (step S17).
In step S18, standby to through stand-by time TWAIT2 shorter than stand-by time TWAIT1
Till, disconnect transistor Q2 and Q4 (step S19) through later in stand-by time TWAIT2.
It addition, stand-by time TWAIT2 can also be identical with stand-by time TWAIT1.
In step S20, differentiate that judging the value of time timer T whether to exceed again judges to forbid again
Period TINT.Initially it is answered as negating (NO), makes the value judging time timer T again increase
The time Δ T (such as 10msec) (step S21) suitable with execution cycle, returns to step S20.
The loop computation of step S20 and the loop computation of S21 and step S11～S13 is with execution cycle
Δ T repeats.
Therefore, when be judged to power supply can not time, again judge forbid that period TINT holds through later
Row judges again, repeats step S11～the process of S13 and S17～S21 afterwards, until being judged to
Till power supply is possible.
In the present embodiment, limit time TPM and be set to the set time (such as 10 seconds),
Judge again to forbid that period TINT is set to generated energy and is likely to occur the time of change, such as 10
About minute.
As above, in the present embodiment, due to the crystalline substance by using voltage conversion circuit 11
Body pipe Q1, Q4 and coil L1 make current flow through the resistance R1 of current detecting, thus metering is sent out
Electricity PM, so the short-circuiting device as shown in need not newly to arrange patent documentation 1, and do not make
With the pyrheliometer as shown in patent documentation 2, therefore, it is possible to judge with simpler composition
The power that solaode can be output by.
Additionally, by flowing through metering electric current ISO when generated energy measures via coil L1, thus
It can be avoided that metering electric current ISO sharply increases, it is possible to the minimal metering needed for judging
Carry out power supply with electric current ISO could judge.Further, due to generated energy PM's
Metering electric current ISO is made to flow through coil L1 during metering, so cutting off electricity as disconnection transistor Q1
During stream, by being also turned on transistor Q2 such that it is able to prevent the generation of excessive counter electromotive force,
It can be avoided that other components being connected with coil L1 are brought bad shadow due to excessive voltage
Ring.
Additionally, when the generated energy PM measured is less than decision threshold PMTH, carry out forbidding too
The generation power of sun energy battery 2 is to the power supply undecidable of the supply of electrical load, from carrying out
This power supply undecidable time lights and have passed through the time point judging to forbid period TINT again,
Again carry out power supply could judge.By have passed through again judge forbid period TINT after carry out
Judge again such that it is able to what the increase etc. of the corresponding insolation amount because irradiating to solaode 2 caused sends out
The change of electricity PM.
In the present embodiment, MPPT controller 12, vehicle control device 10 and resistance R1
Constituting detection unit, resistance R1 and MPPT controller 12 constitute generated energy measurement unit, by MPPT
Controller 12, vehicle control device 10 and voltage conversion circuit 11 constitute voltage changer.
