Abstract
Disclosed in the utility model is a neutral line-free intelligent three-phase rectification voltage adjusting device that comprises a three-phase rectifier bridge unit, a DVR circuit unit, a secondary rectifier unit, an electrolytic capacitor unit, an adjustment unit, and a sampling feedback unit. After the power is switched on, the sampling feedback unit transmits information of a voltage needed by a DC/DC converter to the three-phase rectifier bridge unit and the secondary rectifier unit; after the three-phase power supply is rectified by the three-phase rectifier bridge unit, a current is converted from an alternating current to a direct current, wherein the current that has been processed by the primary rectification is doped with impurities of a sawtooth wave and an alternating current and the like; the direct current directly enters the secondary rectifier unit; and after the secondary rectification, the voltage needed by the DC/DC converter is obtained. According to the utility model, the neutral line-free intelligent three-phase rectification voltage adjusting device with advantages of neutral line-free property, intelligentization, low fault, and random adjustment of the voltage needed by the converter is provided.

Background technology
At present in the three-phase electricity consumption and there is not the occasion of the available interchange neutral line, needing low power DC/DC transducer of access, is the low-voltage equipment power supply.This just means the voltage link of having to use between line, thus rectification and voltage up to about 564V, so high voltage makes some economical DC/DC transducers commonly used can't work at this, even if the DC/DC transducer that can adapt to this environment is arranged, owing to being operated under the high-tension environment, transducer also very easily breaks down.The cost that causes maintenance to the user like this or change will increase greatly.
The utility model content
The utility model mainly provide a kind of low without center line, intellectuality, fault, can adjust arbitrarily a kind of without center line three phase rectifier intelligent voltage adjusting device of transducer demand voltage.
A kind of without center line three phase rectifier intelligent voltage adjusting device by the three-phase commutation bridge unit, the DVR circuit unit, the secondary rectification unit, the electrochemical capacitor unit, adjustment unit, the sampling feedback unit forms, described three-phase commutation bridge unit is by binding post and resistance R 1, the electrochemical capacitor unit, the secondary rectification unit connects, described DVR circuit unit is by binding post and three-phase commutation bridge unit, adjustment unit, the sampling feedback unit connects, the DVR circuit unit will convey to adjustment unit from the required voltage of DC/DC transducer of sampling feedback unit collection, adjustment unit conveys to signal three-phase commutation bridge unit and secondary rectification unit again, so that the voltage after the rectification is fit to the required voltage of DC/DC transducer; Described adjustment unit mainly consists of by adjusting pipe, be connected with electrochemical capacitor unit, secondary rectification unit, DVR circuit unit by binding post, the information function that in time will obtain from the DVR circuit unit is in three-phase commutation bridge unit and secondary rectification unit, guarantee that the voltage after the rectification is consistent with the voltage that the sampling feedback unit provides, to be fit to the voltage requirements of DC/DC transducer.The secondary rectification unit mainly is made of rectifier, and it is connected with DC/DC transducer, sampling feedback unit by binding post, directly exports to the DC/DC transducer.
Behind the plugged, the sampling feedback unit is conveyed to three-phase commutation bridge unit and secondary rectification unit with the information of DC/DC transducer required voltage, three phase mains is after the rectification of three-phase commutation bridge unit, electric current changes direct current into by alternating current, electric current after the rectification impurity such as sawtooth waveforms, interchange that also mixing, direct current directly enters the secondary rectification unit, reaches the required voltage of DC/DC transducer after the secondary rectification; The impurity such as sawtooth waveforms, interchange then reenters the three-phase commutation bridge unit through the electrochemical capacitor unit and carries out rectification, and final the realization is adjusted to the required voltage of DC/DC transducer with voltage.
