Below in conjunction with accompanying drawing in detail technical solutions of the utility model and embodiment are described in detail.
Voltage gives circuit major loop formation components and parts capacitor 5, autotransformer 7 (see figure 1)s of choosing with the car special charger from suitable all-wave constant current, has following voltage vector equilibrium equation to retrain mutually,
=
C+
AT=
C+ K
0 is a supply voltage in the formula,
CBe the voltage of capacitor 5,
ATBe the input terminal voltage of autotransformer 7,
0Being the input terminal voltage of rectifier bridge 8, also is the output end voltage of autotransformer 7, all is vector, and K is the transformation ratio of autotransformer 7.Its voltage adaptive function is so finished.When being recharged storage battery and reducing to 1 (be recharged pressure and drop to 12 volts) by 24 volts by 2, see by 24 volts of voltage power supply states of the former output of charger, charging current is increased, thereby ac-side current also increase, so the voltage drop on the capacitor
CIncrease, but supply voltage is constant, is subjected to the restriction of voltage balance equation, causes
ATReduce (
ATReduce to reduce to finish by its exciting curent), thus
0Be reduced to the nearly 12 volts of magnitudes of voltage that are fit to a charge in batteries.This moment, charging current only slightly increased to some extent, but can be considered as constant substantially.Here it is bears the effect that internal feedback is used for obtaining voltage adaptive (self compensation), keeps the charging constant current by output (charging) electric current.It also is the basis of realizing that choosing is given in the charging constant current.
Requiring to solve to reduce and draw electric current so that can use the problem of resident's mains lighting supply to power supply, is to be finished by the up-flow function of autotransformer 7.But the up-flow effect that obtains, the size of capacitor 5 and autotransformer 7 and the coupling between the transformation ratio are fully certain.This is the key point of technology.Present embodiment (charging voltage is pacified with interior, direct current output 3,6,9 at 24 volts) electric capacity is C
1=25 μ, C
2=50 μ, autotransformer core section S=14.4cm
2, coil 160 circles+108 (output windings), transformation ratio (up-flow ratio) is (160+108)/108=2.5.
This does not have overload and output short-circuit dangerous problem with the car special charger.But mustn't no-load running and accumulator polarity connect instead, otherwise can damage equipment self.For this reason, take wiring indicator light 10 and 13.When just thinking that the clamping connection accumulator polarity is correct, 13 sides are bright for indicator light; When just thinking that indicator light 13 is bright, just allow to plug output plug (plugs and sockets has inserting uniqueness mechanical pins).Just think to connect load (storage battery), 10 sides are bright for indicator light; Just think that indicator light 10 is bright, just allow energized to charge.This is just to preventing that no-load running and polarity from connecing counter having increased and giving anti-property.
Voltage gives circuit major loop formation components and parts capacitor 5, inductance 15 (see figure 4)s of gating with charger from suitable all-wave constant current, has following voltage vector equilibrium equation to retrain mutually,
=
C+
L+
B is a supply voltage in the formula,
CBe the voltage of capacitor 5,
LBe the voltage of inductance 15,
BBeing filled battery tension, all is vector.By the negative internal feedback effect of output (charging) electric current, produce voltage adaptive, keep constant current charge and provide electric current to give selecting function, its principle and process are similar to the car special charger.The function of inductance 15 is the impact of suppression capacitor starting current, the flat ripple of afterflow and increases load capacity.
Compare with the function of universal charger with the car special charger, the former requires low but the voltage adaptive narrow range to power supply capacity, and the latter requires high to power supply capacity, but the voltage adaptive wide ranges respectively has length.But these length but are that use is pursued with suitable mutually separately just.These functions are the results that adopt autotransformer 7 and inductance 15 and capacitor 5 couplings respectively.
The utility model is compared with existing technology, and advantage is: the technical program has voltage adaptive, all-wave Constant-current charge gives and selects function, and the not employment of charging is transferred, and can carry out uncared for charging in night. Can save prison Voltmeter and the ammeter of control. This is that controllable silicon charger and transformer charger are too late. The all-wave constant current The sharp wave of charge ratio controllable silicon charger is beneficial to electrical network and the life of storage battery. To pure capacitance formula charger , the utility model has solved the starting current impact, has improved band and has carried power. Up-flow of the present utility model Function has reduced the requirement of drawing big electric current to power supply, and this comes capacitor charger and controllable silicon charger Say it all is an important advantage. In addition, its reliability, simplicity, inexpensive property all maintain the leading position.
