The control signal that the described control module 12 receiving issues is the second control signal (can be such as low level 0 etc.), then described charging
The equivalent circuit of circuit can be reduced to the circuit structure shown in Fig. 3.
Further it is assumed that (control signal that the described control module 12 receiving issues is first in the first stage
The stage of control signal, the front T/2 stage), flow through electric current (the i.e. described first electric capacity C1 and described second of described charging circuit
The charging current of electric capacity C2, rear T/2 stage) virtual value can be Ic, in second stage (the described control module 12 receiving
The control signal issuing is the stage of the second control signal), flow through described charging circuit electric current (i.e. described first electric capacity C1 with
And the discharge current of described second electric capacity C2) virtual value is Id；The input current assuming described charging circuit can be Iin, described fill
The output current of circuit can be Iout, and the loss power of described charging circuit in the first stage can be Pc, in second stage institute
The loss power stating charging circuit can be Pd, thus, (i.e. first stage+second stage) described charging circuit in whole cycle
Total loss power can be Pt.Further, because the dutycycle in two stages of described charging circuit is always 50% (i.e. the first rank
Section and second stage respectively account for the half of whole cycle), thus total loss power of described charging circuit and two stages
There is the relation shown in formula 2 between the loss power of described charging circuit：
Due to P=I2* R, thus the loss power of first stage and second stage is represented by formula 3 and formula 4：
Pc=Ic 2*(RQ1+RC1+RQ3+RC2) formula 3；
Total loss power of described charging circuit can be drawn by above-mentioned two formula, as shown in Equation 5：
By above formula, you can calculate the loss power of described charging circuit.Specifically, due under normal circumstances, MOS
The conducting resistance of pipe typically can be between 2～20m Ω, the ESR in low-frequency range (1MHZ about) of the capacity cell of more than 10uF
Can be between 2～15m Ω, if assuming the R in this utility model embodimentQ1=RQ2=RQ3=RQ4=15m Ω, RC1=RC2=
10m Ω, then can calculate total loss power of the charging circuit described in this utility model embodiment, as shown in Equation 6：
Pt=0.025*Ic 2+0.004*Id 2Formula 6；
It is further assumed thatId=Iout(it should be noted that IcAnd IdValue can pass through practical experience
It is worth to, do not repeat herein), thus total loss power of described charging circuit also can be represented by formula 7：
Pt≈0.0165*Iout 2Formula 7；
In sum, total loss power of the charging circuit described in this utility model embodiment can be by the described electricity that charges
The output current on road determines.For example, it is assumed that a charging circuit is (only to include a charge pump conversion electricity in described charging circuit
As a example road 14) be output as 4V/4A (i.e. output voltage is 4V, and output current is 4A), then can be calculated described charging circuit
Total loss power can be 0.264W.It should be noted that the conversion efficiency due to circuitThus also can enter

Change efficiency, that is, reduce the energy loss of charging circuit, it is achieved thereby that real large current charge, effectively accelerate described
The charging rate of charging circuit, reduce the charging interval of described charging circuit, improve the charge efficiency of described charging circuit.
Further, due to the conducting resistance of switch element itself and be not zero, thus, when switch elements in series is in circuit
When middle, pressure drop occurs at the two ends of switch element, this results in the output voltage of described charging circuit and fills described in being not equal to
The half (i.e. VOUT ≠ VIN/2) of the input voltage of circuit.
But, for electric current, due to do not exist in described charging circuit can loss current inductance element (or electricity
Resistance element), thus the output current of described charging circuit can always remain as 2 times of the input current of described charging current, that is,
Iout=2*Iin.Therefore, the output voltage of described charging circuit can be determined according to the size of the output current of described charging circuit
Size, to further determine that the size of the input voltage of described charging circuit.
For example, it is assumed that the charging voltage of the battery of terminal unit is Vbat (output voltage of the charging circuit needing),
Charging current is Ibat (output current of the charging circuit needing), and the input voltage of described charging circuit is Vc, input electricity
Flow for Ic, input power is Pin, output is Pout, blood pressure lowering conversion efficiency is η.Then according to Ic=Ibat/2 (i.e. Ibat=
2*Ic), Pout=Pin* η, Pout=Vbat*Ibat and Pin=Vc*Ic, can obtain Vc=2*Vbat/ η, thus can determine that institute
State the input voltage (i.e. relational expression between the output voltage of described charging circuit and input voltage) of charging circuit, to this
Do not repeat.
That is, using the charging circuit described in this utility model embodiment to terminal unit (as mobile phone, flat board electricity
Brain etc.) etc. when being charged, can first determine that the charging voltage of battery and the charging current in described terminal unit, Ran Houke
According to described charging voltage and described charging current determine to described terminal unit charge adapter output voltage and
Output current, if desired for be Vc=2*Vbat/ η using output voltage, output current be the adapter of Ic=Ibat/2 to described
Terminal unit is charged.Thus ensure that safety and the high efficiency of whole charging circuit, this utility model embodiment pair
This is not limited in any way.
Likewise, it is assumed that may include the individual charge pump translation circuit 14 of M (M >=2) in described charging circuit, due to each charge pump
Translation circuit is parallel with one another, thus total electrical charge pump translation circuit (is formed after multiple charge pump translation circuit parallel connections
Circuit) equivalent resistance can reduce further, and then the larger electric current of described charging circuit output can be made, that is, realize real
The charging of high current, accelerates charging rate, reduces the charging interval, improve charge efficiency.Now, if it will again be assumed that the electricity of terminal unit
The charging voltage in pond is Vbat, and charging current is Ibat, then can determine that each charge pump translation circuit in described charging circuit
Input voltage can be all Ic=Ibat/ (2*M) for Vc=2*Vbat/ η, input current, this is not repeated.
