The diagram demonstrates an extremely very simple voltage stabilizer design which are able to maintain massive output power approximately 5 to 10kva. Voltage stabilizer on other hand is equipment that stabilizes the AC voltage which is usually fluctuating.
The rectifier output voltage is filtered by capacitor. What is circuit diagram and pcb layout for this project. I need a 5kva voltage stabilizer circuit with atleast 3 or 4 relays using ic either Lm or dual timer with indicators of boost buck and normal voltage.

Automatic voltage stabilizer circuit diagram. Block Diagram of Stabilizer Voltage stabilizer can be broadly categorized as AC voltage stabilizer DC voltage stabilizer and Automatic voltage stabilizer. Manual transformers are good for jobs where the equipment is being attended to personally such as while viewing a TV.
This circuit diagram includes 2-relay 3-relay with IC and without IC and with high voltage auto cut. The application of SSR or solid state relays tends to make the output stage convenient to configure and very precise — thanks to the latest SSRs which are usually. You can troubleshoot or construct a stabilizer by using the following circuit diagrams.
Voltage tripler is the circuit where we get the thrice of the peak input voltage like if the peak voltage of ac voltage is 5 volt we will get 15 volt dc at the output. Also an automatic transformer would be unacceptable for viewing a TV in an area where fluctuations are rapid because every time a relay in the automatic voltage regulator changes steps.
Sometimes a variation of voltage or spikes appear on an AC line if we use a voltage stabilizer then the extra high voltages or low voltages can cause no problem to the appliances. Transformer steps down the AC source voltage to 12V. Dear all here is i am attaching here 2 circuits for AC staiblizer can any one explain their accuracy and also provide PCB layout design which can i print on a blank PCB. Then the transformer output is rectified by bridge rectifier.
This module has a knob that adjusts the voltage which is more accurate in the circuit. This would be the only variable resistor that we have used in the circuit and it is needed because there can be a lot of discrepancies in various components and their outputs in the circuit. The outputs can be affected by the tolerance in the resistors and variations in the forward drop voltages of the diodes, and also by many other factors. We will connect the variable resistor in our voltage divider circuit and by changing the resistance values we can get the required output.
The variable resistor is not reliable in this circuit and under the conditions of varying high and low voltages, we need consistency in the operation of this circuit for longer periods of time therefore we decided to use no variable resistor in the final product. When the microcontroller enters the calibration mode, the modified input voltage is shown by the controller. We can measure the real voltage by using a voltmeter.
We change the variable resistance and a different voltage is displayed by the microcontroller. A constant is also introduced which is multiplied with the whole expression and when we change the value of variable resistor then the constant value also changes which can be seen by the seven segment display.
When the controller starts, it checks for the calibration. The constant value has been stored in the EEPROM, the controller retrieves the data and now this value will be used in all the further voltage calculations.
Upon starting of microcontroller for the very first time, it waits for the calibration, if the switch is pressed and calibration is done then the switch gets opened and constant is stored in EEPROM and further operations are carried out.
After the successful calibration, we can now remove the switch and the variable resistor from the circuit. The switch and variable resistor can only be needed now if we want to recalibrate the circuit, otherwise they are not required in the circuit anymore. The above configuration shows the different tappings of transformer with relays. The switching of input is done between V, V and V while for output the tappings are V and V. We have used a simple autotransformer in this circuit.
An auxiliary winding is used to power the circuitry and the turns ratio have also been shown:. Both parts of circuit diagram of automatic voltage stabilizer is shown below. You can use these circuits. For the microcontroller circuit, we use an external crystal of 4 MHz. A 5V DC input is used to power the microcontroller.
The auxiliary winding of autotransformer is of This voltage will not vary much because the circuit and the relays will work to regulate this voltage also. This AC is converted to DC with the help of a rectifier and then a capacitor filters it.
A voltage regulator is also used which will take in the filtered DC. A decoupling capacitor is also used and is placed close to the microcontroller. The DC voltage that goes into the is used in powering the relays also.
But not directly, as the voltage is still a bit higher than the rated voltage of relays. So we pass this voltage through four diodes in series which will reduce the voltage by 2. The microcontroller controls the switching of relays, but it cannot provide the current required to operate the relays therefore we use transistors to amplify the value of current. Coming to the seven segment display, the three seven segments displays used in the circuit are switched one after the other which minimizes the pins required to drive them.
But this happens so fast that we cannot comprehend it just by looking at them. The refresh rate is Hz, that is, the display refreshes times in a second.
To achieve the required brightness, we have connected seven transistors with the seven segment displays. We have used three LEDs in the circuit also which shows the delay, low cut or high cut or simply normal mode of the controller. This was the whole process of making an automatic voltage stabilizer at home. By following the steps correctly, we hope that you can make one at home too and you can also modify it according to your reqirements.
