Static Voltage Stabilizer Working Principle

Static voltage regulator definition.

Static voltage stabilizer working principle. The input voltage will add with the voltage at transformer that is 40 v. It is very common to have a voltage stabilizer with refrigerators air conditioners televisions furnace equipments micro oven music systems washing machines etc. The basic study of svr is. 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.

Basically it works on the same principle as that of. A static voltage rectifier has no moving parts as in case of servo based voltage stabilizers. As the name suggests static voltage stabilizer doesn t have any moving parts as a servo motor mechanism in case of servo stabilizers. The static voltage stabilizers proffer improvement on slow servo controlled stabilizer.

Working and analysis of svs static voltage stabilizer is implemented on piccolo f28069 dsp based board. This is because each and every electrical appliance is designed to operate under a specific. The main intention behind the usage of voltage stabilizers is to protect the devices against voltage fluctuations. Lets consider example that a load of 50kva 220v is connected at output of static voltage regulator.

It uses power electronic converter circuit to achieve voltage regulation rather than a variac in case of conventional stabilizers. These static voltage stabilizers have very high accuracy and the voltage stabilization is within 1. Next the operation of buck mode. The 40 v is generated by the pwm using igbt.

The input voltage of stabilizer is 180 v and the output is 220 v. In this mode pwm is generated opposite phase. Their circuit consists apparatus like transformers capacitors resistors transistors magnetic amplifiers etc. 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.

Here you can see the block diagram of voltage stabilizer in the below figure. The input voltage is 250 v and the output is 220 v. This control board continuously senses input voltage output voltage load current and igbt. 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.

And suppose high voltage of 250v is available at input line which needs to be corrected to 220v. It uses a power electronic converter circuit to stabilize the voltage. The regulator which do not have any rotating parts such type of regulator is called static voltage regulator. 13 static voltage stabilizers.

When dsp control board senses values of input voltage output voltage load current and igbt current.
