Make a Simple Homemade Automatic Mains Voltage Stabilizer Circuit


Voltage stabilizer is a device which helps to regulate the AC mains input and produces a stable voltage at its output. The output thus serves to protect the connected load from the dangerous input AC fluctuations. A nice little voltage stabilizer circuit can be built by anyone having some knowledge of electronics at home with the help of the instructions provided here. Let’s learn it in a step wise manner:

How the circuit of this mains automatic voltage stabilizer functions?

Plaese refer the CIRCUIT DIAGRAM


Looking at the figure, we find that the whole circuit is built around the IC 741 which is probably one of the most popular op amp among the many electronic hobbyists.
The IC here performs the function of a comparator that is comparing a varying voltage source with a fixed reference voltage.
The fixed reference voltage is provide at its inverting input while the varying voltage which actually is the sample voltage of our fluctuating mains voltage is introduced to it non inverting input via a preset.
The preset is set in such a way that the IC trips or flips its output at a particular suitable threshold of the input voltage, we’ll discuss in the later part of the article.
The output of the op amp is fed to a transistor driver which actuates a relay mechanism.
