    Main components :

    Buck/boost transformer


    Often referred to as 'booster' transformer, it is a standard dry-type transformer with the secondary winding connected in series to the mains and the primary winding supplied by the voltage regulator.


    Voltage regulator

    Basically, it is an autotransformer with continuously variable transformer ratio. The voltage intake varies depending on the position of the rolling contacts; therefore the voltage supplied to the booster transformer primary winding also varies. Being the voltage across the regulator contacts (and consequently that on the secondary winding of the booster transformer) either in phase or in opposition to the supply voltage, it is then added or subtracted to the supply voltage, thus compensating its variations.

    Auxiliary circuit with a microprocessor

    The DSP (Digital Signal Processor) microprocessor-based control circuit (specifically designed for
    drives with the totally digitalized signal) compares the output voltage value to the reference one sampling it 2000 times per second.
    When an anomaly is detected, the controller drives the voltage regulator gear motor. By doing so, the
    regulator rollers change their position thus varying the voltage drawn and supplied to the buck/boost
    transformer primary winding. The input voltage variation is therefore automatically compensated.
    The control system operates so that the output accuracy is ±0.5%. The microprocessor is fitted with the
    soft stop function enabling a precise positioning of the regulator rollers regulation to work smoothly
    even in case of strong fluctuation of the input voltage.

    What's the difference of stable range and working range?

    How to choose the capacity of the voltage stabilizer:

    Principles

    The voltage stabilizer and the voltage regulator are chosen according to the current:

    1 Continuous working current is smaller than the rated current of the voltage stabilizer or voltage regulator, Better to have a design margin of 20%.


    2 The loads start current is smaller than 5 times of rated current of the servo voltage stabilizer with the roller brush and columnar transformer. or 2.5 times the servo voltage stabilizer with a flat brush, 2 times the static voltage stabilizer.


    How to choose the capacity of the voltage stabilizer:

    Loads Rated current:

    Single phase:

    Rated current In=Pn/(Vn*cosφ)

    Three phase:

    Rated current In= Pn/(1.732*Vn*cosφ)


    Note:

    Pn — Load capacity(kW),

    Vn — Rated voltage(V), Tt is Line to Line voltage in three phase system

    Cosφ — Power factor.


    How to choose the capacity of the voltage stabilizer:

    Loads surge current:

    Three phase(Motors):

    1 Direct start: I(tmax)= In total + In(max)*6

    2 Autotransformer start: I(tmax)= In total + In(max)*3

    3 Star-Delta start: I(tmax)= In total + In(max)*3

    4 Variable Frequency start: I(tmax)= In total + In(max)*2

    5 Soft start: I(tmax)= In total + In(max)*3


    Note:

    I(tmax)— The max start current.

    In total — The total rated currents of the loads

    In(max)— The max starting current of the motor.
