Why Does The Larger The Voltage Regulation Range Of A Dynamic Regulator, The Higher The Cost?

Dynamic Voltage Regulator (DVR) is an electrical power equipment that converts fluctuating voltage into stable and small fluctuation voltage. However, the voltage that the voltage stabilizer can stabilize is not all voltage fluctuation widths that can be tolerated and stabilized. But not all voltage stabilizers cannot stabilize voltages with large fluctuations. Like voltage fluctuations, voltage stabilizers have a range value, which is what we call the voltage input range value of the voltage stabilizer. The larger the range value of the voltage stabilizer, the higher the stable voltage fluctuation amplitude. On the contrary, if the input range value is smaller, the stable voltage amplitude is smaller. Such an amplitude value of the voltage stabilizer is called positive and negative percentage. The positive and negative percentage of the voltage stabilizer shows the voltage range value that the voltage stabilizer can stabilize. If the voltage fluctuation value in our area is large, then we need a higher voltage range value of the voltage stabilizer. The standard voltage range of Tianhengda's voltage stabilizer is 20%. Of course, a large range of voltage stabilization requires a larger compensation transformer, and the cost of our voltage stabilizer will also increase.
