Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 3, Figure 4, the main circuit structure that is used for the power supply that storage battery changes into of the present invention, comprise: three-phase rectifier transformer 1, three-phase rectifier transformer 1 is connected with the rectification thyristor group 2 that six controllable silicon D1～D6 forms by three secondary output ends, is serially connected with smoothing reactor L4 in the output loop of rectification thyristor group 2; Between three secondary output ends of three-phase rectifier transformer 1, also be serially connected with by three inductance L 1, L2, L3 and three absorption circuits 3 that capacitor C 1, C2, C3 constitute, absorption circuit 3 has two kinds of connections usually, first kind of connection as shown in Figure 3, three capacitor C 1, C2, C3 join end to end by the triangular form connection, the end of three inductance L 1, L2 and L3 links to each other with three secondary output ends of three-phase rectifier transformer 1 respectively, and the other end of three inductance L 1, L2 and L3 links to each other with three end points in the triangular form connection respectively; Another kind of connection as shown in Figure 4, three capacitor C 1, C2, C3 are serially connected by wye connection, that is: the end of three capacitor C 1, C2, C3 is together connected with each other, the other end of three capacitor C 1, C2, C3 links to each other with the end of three inductance L 1, L2, L3 respectively, and the other end of three inductance L 1, L2, L3 links to each other with three secondary output ends of three-phase rectifier transformer 1 respectively.
The difference of the main circuit described in main circuit of the present invention and the background technology is: of the present invention Main circuit behind the absorption circuit that inductance suitable on the secondary coupling of rectifier transformer and electric capacity consist of, can To reduce reactive power, reduce the harmonic component of electrical network, make the current waveform of input level off to sine wave, with The time can also improve power factor, the electricity charge fine of avoiding producing because reactive power is excessive, even more important Be: can reduce the electric current of rectifier transformer input, also can reduce the apparent energy of rectifier transformer, from And the design power of rectifier transformer is reduced, thereby greatly reduce the manufacturing cost of rectifier transformer.
