Abstract
The invention discloses a high-frequent dual-splitting rectifying transformer, which comprises a transformer primary side, a transformer iron core, a transformer secondary side, a silicon stack rectifying bridge and a capacitor. The transformer primary side connected with mono-phase alternating current is connected with the silicon stack rectifying bridge by the transformer secondary side after being subjected to voltage-reducing by a transformer, and pulse direct current rectified by the silicon stack rectifying bridge is outputted as direct current with a stable voltage value after passing the capacitor. The high-frequent dual-splitting rectifying transformer has the advantages of realizing high-frequency running, thus facilitating reducing the size of the transformer. In addition, the transformer can output larger current, thus realizing the function of fast charging.

Embodiment
The two division rectifier transformers of a kind of high frequency, see Fig. 1, single-phase high-frequency ac is electrically connected to the former limit 3 of transformer, after the transformer step-down, by transformer secondary 4 output high-frequency alternating currents, the high-frequency alternating current of each winding output of transformer secondary 4 carries out rectification output by silicon stack rectifier bridge 5, pulsating dc voltage after the rectification obtains the direct voltage harmonic wave still less through filter capacitor 6, voltage is galvanic current more, and Shu Chu direct current carries out parallel connection at last, obtains the big electric current of the last output of transformer.
In Fig. 2, the former limit 3 of transformer and transformer secondary 4 are wrapped in the both sides of the transformer core of being made by ferrite 2 by bunch, and wherein transformer secondary 4 is formed by two groups of identical winding techniques of the number of turn.The former limit 3 of transformer is connected to transformer end of incoming cables 1 by copper bar; Transformer secondary 4 was received silicon stack rectification module 5 before this and was carried out rectification, and the voltage after the rectification is by electric capacity 6 filtering voltage regulations, the output 7 that last secondary two windings are connected in parallel and receive transformer.The former limit 3 of the transformer that coiling is good and transformer secondary 4 usefulness transformer folders 8 are fixed up, and last all modules are placed in the transformer case 9.
The two division rectifier transformers of this high frequency belong to single-phase electricity input, single-phase output behind the transformer step-down rectifier.Iron core adopts Ferrite Material, to satisfy high-frequency requirement.The number of turn on the former limit of transformer is 16 circles, and secondary adopts the winding of two groups of identical numbers of turn, and the number of turn of each winding is 4 circles.Each winding of transformer secondary is received the silicon stack rectifier bridge and is carried out rectification, the electric capacity in parallel of the voltage after the rectification.The voltage of last two windings output is in parallel again.After each winding rectification and an electric capacity, utilize self charge-discharge characteristic to make output ripple direct current mean value be adjusted into level and smooth direct current peak value to realize electric capacity, and the remaining alternating component of filtering.
Volume of the present invention is little, in light weight, efficient is high, and can stable operation, can realize exporting big electric current, can satisfy the needs of quick charge.
