One end of lamp L is ground connection, and the other end is connected with the lamp terminal of battery charging plant 100.This lamp L is such as the lamp such as headlight, back light of motorcycle.In this case, owing to opening the action of distance light (high beam) etc., the load change (increase) of lamp L.
Load R is connected between ground connection and accumulator terminal TB.This load R is such as the vehicle load etc. needing power supply on motorcycle.
In addition, battery charging plant 100 carries out rectification the alternating current that the lead-out terminal from single-phase alternator A exports, and controls based on the charging of the storage battery B of single-phase alternator A and lighting (power supply supply) of lamp L.
Here, as shown in Figure 1, battery charging plant 100 such as has: generator terminal TA, lamp terminal TL, accumulator terminal TB, earth terminal TE, the first thyristor (the first switch (switch) element) S1, the second thyristor (second switch element) S2, the 3rd thyristor (the 3rd switch element) S3 and control circuit CON.

The anode (first node) of the second thyristor S2 is connected with generator terminal TA, and negative electrode (Section Point) is connected with accumulator terminal TB.
Here, as will be described later, when the output voltage of generator terminal TA is positive polarity (the second polarity), when the battery tension of storage battery B is less than assigned voltage, this second thyristor S2 opens.Like this, the part of the positive side of the output voltage of single-phase alternator A is supplied to storage battery B, and storage battery B is charged.
In addition, when output voltage is positive polarity, when the storage battery of storage battery B is pressed in more than assigned voltage, the second thyristor S2 closes.Like this, storage battery B is made to be overcharged.
The anode (first node) of the 3rd thyristor S3 is connected with generator terminal TA, and negative electrode (Section Point) is connected with lamp terminal TL.

Like this, when the effective value of modulating voltage or mean value are less than threshold voltage, in order to make the effective value of modulating voltage or mean value close to target voltage, the 3rd thyristor S3 carries out complementary action.Therefore, the performance of the 3rd thyristor S3 can be lower than the performance of the first thyristor S1.

In addition, control circuit CON, based on the voltage of each terminal TA, TL, TB, TE, by outputing signal to the grid (gate) from the first to the three thyristor S1, S2, S3, controls the action from the first to the three thyristor S1, S2, S3.
This control circuit CON, such as based on the voltage of accumulator terminal TB and earth terminal TE, detects the voltage of the storage battery of storage battery B.
In addition, control circuit CON, such as based on the voltage of lamp terminal TL and earth terminal TE, calculates the comparison value as effective value or mean value of the modulating voltage of lamp terminal TL.Such as, control circuit CON calculates effective value or the mean value of the potential difference between lamp terminal TL and earth terminal TE, and the value this calculated exports as comparison value.
In addition, control circuit CON, such as based on the voltage TE of generator terminal TA and earth terminal, detects the polarity of the voltage (output voltage of single-phase alternator A) of generator terminal TA.Such as, control circuit CON, from the electric potential relation between generator terminal TA and earth terminal TE, detects the polarity of the voltage (output voltage of single-phase alternator A) of generator terminal TA.
Here, as shown in Figure 1, this control circuit CON has: computing circuit AC, threshold voltage generative circuit TVG, differential voltage generative circuit DVG, the first comparison circuit C1, the second comparison circuit C2 and battery tension Circuit tuning BC.
Computing circuit AC detects the modulating voltage of lamp terminal TL, then calculates and exports the comparison value as effective value or mean value of the modulating voltage be detected.
Threshold voltage generative circuit TVG generates and exports threshold voltage.
Differential voltage generative circuit DVG generates differential voltage, and exports the target voltage obtained by adding this differential voltage on threshold voltage.
The result that the target voltage that first comparison circuit C1 exports according to the comparison value exported by computing circuit AC and differential voltage generative circuit DVG compares, and the polarity of generator terminal TA voltage (output voltage of single-phase alternator A), to the gate output signal of the first thyristor S1.
Such as, when output voltage is negative polarity, when comparison value is less than target voltage, first comparison circuit C1 is in order to open the first thyristor S1, to the gate output signal of the first thyristor S1, on the other hand, when comparison value is less than target voltage, in order to close the first thyristor S1, to the gate output signal of the first thyristor S1.
In addition, when output voltage is positive polarity, the first comparison circuit C1 in order to close the first thyristor S1, to the gate output signal of the first thyristor S1.

Such as, when output voltage is negative polarity, battery tension Circuit tuning BC in order to close the second thyristor S2, to the gate output signal of the second thyristor S2.
In addition, when output voltage is positive polarity, when battery tension is less than assigned voltage, battery tension Circuit tuning BC is in order to open the second thyristor S2, to the gate output signal of the second thyristor S2, on the other hand, when storage battery is pressed in more than assigned voltage, in order to close the second thyristor S2, to the gate output signal of the thyristor S2 of second.
Secondly, an example of the accumulator charging method based on battery charging plant 100 had in the battery charging system 1000 of above structure is described.
Here, Fig. 2 is the oscillogram of an example of the waveform of the action of the battery charging system 1000 of display shown in Fig. 1.In addition, in fig. 2, as a wherein example, to describe the situation of the effective value of modulating voltage as comparison value, but also can using the mean value of modulating voltage as comparison value.
As shown in Figure 2, the output voltage of the generator terminal TA exported from single-phase alternator A be the situation of negative polarity (such as, moment t0 ~ t2) under, due to the effective value of the modulating voltage of lamp terminal TL as comparison value less than target voltage (moment t0), therefore control circuit CON opens first thyristor S1(moment t1 ~ t2).
Like this, the part of the minus side of the output voltage of single-phase alternator A is supplied to lamp L.
In addition, in the situation (moment t0 ~ t2) that this output voltage is negative polarity, control circuit CON closes the second thyristor S2 and the 3rd thyristor S3(moment t0 ~ t2).
Afterwards, in the situation (such as, moment t2 ~ t4) that output voltage is positive polarity, because the battery tension of storage battery B is not less than assigned voltage (illustrating at this), therefore control circuit CON opens second thyristor S2(moment t3 ~ t4).At this moment, output voltage is battery tension V
bATwith the voltage VT of the second thyristor S2
s2sum.
Like this, the part of the positive side of the output voltage of single-phase alternator A is supplied to storage battery B, and storage battery B is charged.
Further, in the situation (moment t2 ~ t4) that this output voltage is positive polarity, due to comparison value (effective value) (moment t2) more than threshold voltage, therefore control circuit CON closes the 3rd thyristor S3(moment t2 ~ t4).
In addition, in the situation (moment t2 ~ t4) that this output voltage is positive polarity, control circuit CON closes the first thyristor S1.
Afterwards, in the situation (such as, moment t4 ~ t5) that output voltage is negative polarity, because comparison value (effective value) is less than target voltage (moment t4), therefore control circuit CON opens first thyristor S1(moment t4 ~ t5).
Like this, the part of the minus side of the output voltage of single-phase alternator A is supplied to lamp L.
In addition, when this output voltage is negative polarity, control circuit CON closes the second thyristor S2 and the 3rd thyristor S3(moment t4 ~ t5).
Afterwards, in the situation (such as, moment t5 ~ t8) that output voltage is positive polarity, because the battery tension of storage battery B is not less than assigned voltage (illustrating at this), therefore control circuit CON opens second thyristor S2(moment t6 ~ t8).
Like this, the part of the positive side of the output voltage of single-phase alternator A is supplied to storage battery B, and storage battery B is charged.
Further, in the situation (moment t5 ~ t8) that this output voltage is positive polarity, because comparison value (effective value) is less than threshold voltage (moment t5), therefore control circuit CON opens the 3rd thyristor S3(moment t7 ~ t8).
Like this, the part of the positive side of the output voltage of single-phase alternator A is supplied to lamp L.Consequently, the effective value of modulating voltage can be made more close to target voltage.
In addition, in the situation (moment t5 ~ t8) that this output voltage is positive polarity, it is the first thyristor S1 that control circuit CON closes.
In addition, when output voltage is positive polarity (not illustrating in the example in figure 2), when the storage battery of storage battery B is pressed in more than assigned voltage, control circuit CON closes the second thyristor S2.Like this, storage battery B can not be overcharged.
After, battery charging plant 100, by repeatedly same action, while storage battery B is charged to assigned voltage, makes the effective value of modulating voltage or mean value maintain state closer to target voltage.
Here, Fig. 3 is the figure of an example of the relation of display storage battery B between the rotation number and the effective value of modulating voltage of the single-phase alternator A of storage battery full state.In addition, Fig. 4 is the figure of an example of the relation shown between the rotation number of storage battery B state single-phase alternator A of (battery tension does not arrive assigned voltage) when being charged and the effective value of modulating voltage.
As shown in Figure 3, Figure 4, in battery charging plant 100A in the past, if the revolution of single-phase alternator A rises, and shorten during opening the first thyristor S1, then the effective value of modulating voltage declines.
When the power consumption of lamp L becomes large, the tendency that the effective value of this modulating voltage declines becomes obvious.Further, when the voltage of storage battery is less than assigned voltage, and time elongated during opening the second thyristor S2 (Fig. 4), this tendency becomes obvious.
On the other hand, in the battery charging plant 100 that execution mode relates to, even if the revolution of single-phase alternator A rises, and the time of opening the first thyristor S1 shortens, also can by the 3rd thyristor S3 to lamp L secondarily supply power, therefore the effective value of modulating voltage reduces (Fig. 3, Fig. 4) hardly.
Like this, in the battery charging plant that execution mode relates to, even such as single-phase alternator A generation power relative to lamp L power consumption not fully in situation, also can suppress the decline of modulating voltage effective value.
As above, battery charging plant of the present invention uses single-phase alternator to control the power supply supply of charge in batteries and lamp.This battery charging plant has: and between ground connection, be connected with the generator terminal of coil of single-phase alternator A; And be connected with the lamp terminal of lamp between ground connection; And be connected with the accumulator terminal of storage battery between ground connection; Negative electrode and generator end sub-connection, the first thyristor that anode is connected with lamp terminal TA; Anode and generator end sub-connection, the second thyristor that negative electrode is connected with battery terminal; Anode and generator end sub-connection, negative electrode is connected the 3rd thyristor with lamp terminal; And the control circuit of the action of control the first to the three thyristor.
Further, when the output voltage of the generator terminal exported from single-phase alternator is negative polarity, when the effective value of the modulating voltage of lamp terminal or mean value as desired value less than comparative voltage time, the first thyristor opened by control circuit.On the other hand, when output voltage is positive polarity, when comparison value is less than the threshold voltage lower than target voltage, the 3rd thyristor opened by control circuit, when the battery tension of storage battery is less than assigned voltage, opens the second thyristor.
Like this, the part of the positive side of the output voltage of single-phase alternator is supplied to storage battery, and storage battery is charged.The part of the minus side of the output voltage of single-phase alternator is supplied to lamp.Further, when the effective value of modulating voltage or mean value are less than threshold voltage, at least one part of the part of the positive side of the output voltage of single-phase alternator is secondarily supplied lamp.
Therefore, such as, in lamp load variation, when modulating voltage declines, modulating voltage can be made quickly close to target voltage.
That is, according to battery charging plant of the present invention, can single-phase alternator be passed through, while charging a battery, suppress the brightness of lamp to decline.
