Static voltage regulator definition.
Static voltage stabilizer working principle.
As the name suggests static voltage stabilizer doesn t have any moving parts as a servo motor mechanism in case of servo stabilizers.
Their circuit consists apparatus like transformers capacitors resistors transistors magnetic amplifiers etc.
These static voltage stabilizers have very high accuracy and the voltage stabilization is within 1.
It uses power electronic converter circuit to achieve voltage regulation rather than a variac in case of conventional stabilizers.
This is because each and every electrical appliance is designed to operate under a specific.
This control board continuously senses input voltage output voltage load current and igbt.
Buck mode working of static voltage stabilizer.
A voltage stabilizer is a powerful appliance used to feed constant voltage current to electrical appliances protecting them from damage because of voltage fluctuations and erratic power supply.
The static voltage stabilizers proffer improvement on slow servo controlled stabilizer.
The basic study of svr is.
Next the operation of buck mode.
Here you can see the block diagram of voltage stabilizer in the below figure.
And suppose high voltage of 250v is available at input line which needs to be corrected to 220v.
The input voltage is 250 v and the output is 220 v.
The main intention behind the usage of voltage stabilizers is to protect the devices against voltage fluctuations.
The working principle of a voltage stabilizer is very simple its main function to keep stable the output voltage by increasing or decreasing the voltage level according to the unstable input voltage.
It is very common to have a voltage stabilizer with refrigerators air conditioners televisions furnace equipments micro oven music systems washing machines etc.
The regulator which do not have any rotating parts such type of regulator is called static voltage regulator.
The input voltage of stabilizer is 180 v and the output is 220 v.
In event of short circuit at output of static voltage stabilizer load current increases exponentially high which automatically get sense by dsp controller and it cuts output switches.
In static voltage stabilizer dsp control board continuously senses input voltage output voltage igbt current and load current as part of working principle.
So 180 v 40 v 220 v.
When dsp control board senses values of input voltage output voltage load current and igbt current.
The input voltage will add with the voltage at transformer that is 40 v.
It uses a power electronic converter circuit to stabilize the voltage.
13 static voltage stabilizers.
In this mode pwm is generated opposite phase.
Basically it works on the same principle as that of.
Lets consider example that a load of 50kva 220v is connected at output of static voltage regulator.
