功能：调压器系列产品是针对农网等供电半径长，负荷变化大而造成的供电末端电压低的现场而开发的产品，该产品对后端电压起到调节﹑稳压的作用，可有效解决配电网末端低电压的问题。
二、工作原理
该系列产品主要由交流旁路单元、功率变压器、整流单元、逆变单元、输入输出配电及保护、通讯单元等组成。
当市电输入电压在允许波动范围内，系统工作在交流旁路模式；当负荷加重导致“低电压”现象或者负荷降低导致“高电压”现象时，系统从旁路模式切换到整流逆变模式。整流单元由数字信号处理器控制IGBT模块输出稳定的内部直流电压，同时整流单元具有稳压功能，能够抑制输入市电电压的波动，逆变单元根据当前市电电压大小，计算出需要补偿电压，逆变单元输出相应电压通过变压器叠加到市电上，一起供给负载，从而解决了“低电压”或“高电压”问题。

Function:The voltage regulator series products are developed for sites with long power supply radius and large load changes, such as rural power grids, resulting in low voltage at the end of the power supply. This product plays a role in regulating and stabilizing the back-end voltage, effectively solving the problem of low voltage at the end of the distribution network.
2、 Working principle
This series of products mainly consists of AC bypass units, power transformers, rectifier units, inverter units, input-output distribution and protection, communication units, etc.
When the input voltage of the mains is within the allowable fluctuation range, the system operates in AC bypass mode; When the increase in load leads to the phenomenon of "low voltage" or the decrease in load leads to the phenomenon of "high voltage", the system switches from bypass mode to rectifier inverter mode. The rectifier unit is controlled by a digital signal processor to output a stable internal DC voltage from the IGBT module. At the same time, the rectifier unit has a voltage stabilization function, which can suppress fluctuations in the input mains voltage. The inverter unit calculates the required compensation voltage based on the current mains voltage, and the corresponding voltage output by the inverter unit is superimposed on the mains voltage through a transformer to supply the load together, thus solving the problem of "low voltage" or "high voltage".
