Abstract
Specially, the invention is related to charging machine for charging accumulator in use for electric motor cars. The disclosed charging machine solves following main issues: safety isolation between AC side and DC side of rectification equipment without transformer; raising use ratio for AC power supply; lowering requirement of withstanding voltage for rectification parts in main circuit; reducing self wasting and labor strength for maintaining accumulators; prolonging service life of accumulators etc. main technical characters are: using unidirectional controllable silicon as isolated component, no transformer, continuously adjustable output voltage.
Description
Technical field
The present invention belongs to the charger that charge in batteries is used, particularly the charger used of the charge in batteries on the electric motor car vehicle.
Background technology
Domestic, produce the transless silicon controlled rectifier battery charger as Nanchang radio factory, this machine is the charging that domestic advanced its output waveform of charger particularly is suitable for storage battery, charging effect is good.But this machine has a direct current output directly to be connected with ac power input end, requires the firewire binding post of charger to be connected with zero line with the live wire of AC power respectively with the zero line binding post in use, is never permitted wrong, otherwise electric shock accidents can take place.And for example the patent No. is: CN86207537U silicon controlled rectifier charger, though that root lead that this machine one direct current output is connected with ac power input end, the middle rectifier diode that inserts, also dangerous, equally electric shock accidents can take place also.And the requirement of withstand voltage of thyristor is higher, operates more numerously, if having improperly, is prone to the impact to pipe.For another example: application number: the energy-conservation automatic charger of 90210262.1 condenser types.
Above charger can not be safe and reliable, and be installed in easily on the motor vehicle, and storage battery is carried out on-board charging.
Summary of the invention
The object of the present invention is to provide a kind of esy to use, safe and reliable, small-sized light and handy, efficient is high, cost and the low New-type charge machine of price.
The present invention is achieved in that it comprises that shell, printed circuit board (PCB), power line, output line, rectification circuit 1, voltage stabilizing circuit 2, circuits for triggering 3, amplifying circuit 4, buffer circuit 5, sample circuit 6, light emitting diode display circuit, power line, output line all are welded on the printed circuit board (PCB).Can form the charger that the present invention proposes like this.
Owing to cancel transformer in the operating circuit of the present invention, not only can improve charge efficiency greatly but also can reduce the volume of charger.In addition, charger itself is carried out control automatically in the present invention, as: level pressure, constant current, floating charge, outage automatically, its charge efficiency can reach more than 95%.
Description of drawings
Fig. 1 is the schematic diagram of charger of the present invention;
Fig. 2 is circuit theory diagrams of the present invention.
Embodiment
As shown in Figure 1, input and output are isolated, need not distinguish live wire and zero line with two one-way SCRs, therefore safe and reliable, adopt full control halfwave rectifier, silicon-controlled voltage regulation has reduced the requirement of withstand voltage to the main circuit rectifying component.
As shown in Figure 2, adopt the form of symmetry to provide the half-wave rectifying circuit that is operated in positive half cycle of alternating current and negative half period respectively, utilize one-way SCR that input and output are isolated, thereby making output all is direct current after rectification, its course of work is, when the positive half cycle of alternating current, SCR
1And SCR
2Conducting, during negative half period, SCR
3And SCR
4Conducting, the one tunnel exchanges input, and the two-way direct current goes out to improve greatly charger efficient respectively.
