Assume that the corresponding voltage in one end that Ia is input in current foldback circuit is Vcc, the output voltage values of constant pressure source are V.
So,
The magnitude of voltage of the input in the same direction of operational amplifier A is Vcc；
The magnitude of voltage of the reverse input end of operational amplifier A is Vcc-Ia*R+V；
According to the operation principle of operational amplifier, when the magnitude of voltage of input in the same direction is more than the magnitude of voltage of reverse input end
When, operational amplifier output high level, i.e. Vcc>During Vcc-Ia*R+V, operational amplifier output high level.In the inequality V and
R is known parameter value in current foldback circuit, thus it may be concluded that working as Ia>During V/R, the high electricity of operational amplifier output
It is flat.Comparison controller is detected can trigger the over-current detection protection to equipment to be protected after operational amplifier output high level.
The mistake flow point that V/R is configuration in current foldback circuit can be seen that according to as above conclusion, when Ia is more than the configuration
Mistake flow point when, can trigger and the over-current detection of equipment to be protected is protected.Thus, for the different operation shapes of equipment to be protected

Plus, the rated current summation of each part in place is obtained, the summation for obtaining is crossed into flow point as calculated.
S203：The mistake flow point that flow point configures the first current foldback circuit is crossed according to calculated.
Wherein, the first current foldback circuit is used to carry out over-current detection protection to equipment to be protected.
Using flow point collocation method is crossed in the current foldback circuit shown in Fig. 2, according to the rated power meter of part in place
Flow point was obtained, and the first excessively stream of over-current detection protection was carried out to equipment to be protected according to the configuration of calculated flow point excessively
The mistake flow point of protection circuit.It is according to all portions in equipment to be protected compared to flow point is crossed in current foldback circuit in prior art
What the rated power of part was calculated, it is unadjustable to cross flow point, had that flow point configuration is inaccurate, cannot play to equipment to be protected
The problem of over-current detection protective effect, because the mistake flow point configured in the first current foldback circuit in the present embodiment is that basis is waited to protect
What the rated power of the part in place in shield equipment was calculated, thus the mistake flow point configured in the first current foldback circuit is suitable for treating
The situation various in place of the part in protection equipment, in each case can be accurate for the configuration of the first current foldback circuit
Flow point is crossed, the over-current detection protective effect to equipment to be protected can be preferably played.
Alternatively, equipment to be protected includes essential part and selectable unit (SU), it is determined that part in place include essential part
And/or selectable unit (SU) in place.Now, the mode for excessively stream point being calculated in S202 can obtain each selectable unit (SU) in place
Rated power and/or each essential part in place rated power, and according to the specified work(of each selectable unit (SU) in place
The rated power of rate and/or each essential part in place, was calculated flow point.
Because essential part is the part that must be equipped with equipment to be protected, thus in equipment to be protected course of normal operation
In, essential part is necessarily in place；Because selectable unit (SU) is the part that equipment to be protected can be selected, thus in equipment to be protected just
Often in the course of work, selectable unit (SU) may be in place, it is also possible to not in place.Therefore, perform S201 after, it is determined that part in place
For all essential part and selectable unit (SU) in place.
It should be noted that the quantity of selectable unit (SU) can be one or more, the quantity of essential part can also be one
It is individual or multiple, the quantity of selectable unit (SU) and essential part is not limited in the embodiment of the present invention.Selectable unit (SU) in place
Quantity can for zero, one or more.
When the quantity of selectable unit (SU) in place is zero, although the calculated specified work(for crossing flow point and selectable unit (SU)
Rate is unrelated, but the rated power of selectable unit (SU) was considered during being calculated flow point, and for equipment to be protected
The mistake flow point for carrying out the first current foldback circuit of over-current detection protection is also to cross flow point configuration according to calculated, because
And, the mistake flow point collocation method of first current foldback circuit also should be regarded as falling into protection scope of the present invention.
Alternatively, each selectable unit (SU) in equipment to be protected is also provided with second current foldback circuit.For
One selectable unit (SU), is that its second current foldback circuit for arranging can play the over-current detection protective effect to the selectable unit (SU),
The mistake flow point of second current foldback circuit can be configured according to the rated power of the selectable unit (SU).
In the case where over-current detection protection is carried out to equipment to be protected by the first current foldback circuit, then by second
Current foldback circuit carries out over-current detection protection to each selectable unit (SU), more accurately can carry out excessively stream to each selectable unit (SU)
Detection protection, further enhancing the effect that the over-current detection to selectable unit (SU) is protected.
Wherein, when the mistake flow point of the second current foldback circuit is configured, can be according to the rated power of selectable unit (SU) and specified
Voltage calculates the rated current of selectable unit (SU), according to the excessively stream of the current foldback circuit of rated current configuration second of selectable unit (SU)
Point.
Additionally, can be two or more selectable unit (SU)s in selectable unit (SU) when the second current foldback circuit is arranged
One the second current foldback circuit is set.Such as, certain two selectable unit (SU) would generally be used together, i.e., when one of them optional portion
When part is in place, another selectable unit (SU) is generally also in place.One the second current foldback circuit is set for the two selectable unit (SU)s, no
Can only further enhance the effect protected to the over-current detection of the two selectable unit (SU)s, and be all provided with for each selectable unit (SU)
The scheme for putting second current foldback circuit is compared, it is possible to decrease the components and parts cost of circuit.

The effect of shield.
In S203, need to cross the mistake flow point that flow point configures the first current foldback circuit according to calculated.Due to meter
The situation that the value of the mistake flow point for obtaining is in place to the part of equipment to be protected is related, and part situation in place has various, because
And the first current foldback circuit needs to configure different mistake flow points in different situations when implementing.Obviously, shown in Fig. 1
Current foldback circuit can not meet such requirement, thus the embodiment of the present invention also provides the concrete of the first current foldback circuit
Way of realization.
The form that implements of the first current foldback circuit includes but is not limited to three kinds below：
The first
In the current foldback circuit shown in Fig. 1, the value of the mistake flow point of configuration is equal to V/R, thus in the first overcurrent protection
In circuit can by arranging multiple sampling resistors to change the first current foldback circuit in the mistake flow point that configures.With the first excessively stream
The number of the sampling resistor arranged in protection circuit is for as a example by four, the way of realization of the first current foldback circuit can be such as Fig. 3 institutes
Show.In Fig. 3, one end of each resistance in resistance R1, R2, R3 and R4 of four parallel connections is connected with a switch, the other end
It is connected with the negative terminal of constant pressure source U；One end of each switch is connected with the input of the first current foldback circuit, operational amplifier
The input in the same direction of A is connected with the input of the first current foldback circuit, and reverse input end is connected with the anode of constant pressure source U, fortune

Trigger the over-current detection to equipment to be protected to protect.
In the first current foldback circuit shown in Fig. 3, can pass through four switches of regulation is opened or closed state, realizes
Whether the resistance of switch connection is linked in the first current foldback circuit, and then realizes the mistake in the first current foldback circuit of configuration
Flow point.
Such as, the output voltage of constant pressure source is 50mV, and the resistance of R1, R2, R3 and R4 is respectively 10m Ω, 20m Ω, 30m Ω
With 40m Ω.So, when the mistake flow point for adopting method shown in Fig. 2 to be calculated according to the situation in place of part in equipment to be protected for
During 5A, the resistance of sampling resistor should be 50mV/5A=10m Ω in the first current foldback circuit.Thus the first current foldback circuit
In sampling resistor should be chosen for R1, i.e., the switch connected with R1 should be closure state；For same equipment to be protected, work as portion
Part situation in place changes, when adopting the mistake flow point that method shown in Fig. 2 is calculated for 2.5A, in the first current foldback circuit
The resistance of sampling resistor should be 50mV/2.5A=20m Ω.Thus the sampling resistor in the first current foldback circuit should be chosen for
R2, i.e., the switch connected with R2 should be closure state.
It should be noted that in the first current foldback circuit shown in Fig. 3, the first current foldback circuit is configured every time
When crossing flow point, the quantity of the switch of closure can be one, or it is multiple.Such as, when the method according to Fig. 2 is calculated
Mistake flow point and the output voltage values of constant pressure source when calculating the resistance of sampling resistor and should be R1*R2/ (R1+R2), be connected with R1
Switch and the switch that is connected with R2 should be closure state.
Explanation is needed also exist for, the quantity of sampling resistor in the first current foldback circuit is not done in the embodiment of the present invention
Limit.When implementing, the quantity and volume of part in equipment to be protected is referred to when the quantity and resistance of the sampling resistor of selection
Determine the parameters such as power.
Second
In the current foldback circuit shown in Fig. 1, the value of the mistake flow point of configuration is equal to V/R, thus in the first overcurrent protection
Can be by the mistake flow point in arranging the different constant pressure source of multiple output voltage values to configure the first current foldback circuit in circuit.
So that the number of the constant pressure source of setting in the first current foldback circuit is for four as an example, the way of realization of the first current foldback circuit can
As shown in Figure 4.In Fig. 4, one end of sampling resistor R is connected with the input of the first current foldback circuit, and the other end connects four
Paralleling switch, the switch of four parallel connections is connected respectively with the negative terminal of constant pressure source U1, U2, U3 and U4, i.e., each constant pressure source is with one
Individual switch series connection；The reverse input end of operational amplifier A is connected respectively with the anode of U1, U2, U3 and U4, input in the same direction and
The input connection of one current foldback circuit, the output end of operational amplifier A is connected with comparison controller, and comparison controller is used for
When operational amplifier A is output as high level, triggers the over-current detection to equipment to be protected and protect.
In the first current foldback circuit shown in Fig. 4, can pass through four switches of regulation is opened or closed state, realizes
