In a voltage regulator, which winding is connected to the source voltage?

In a voltage regulator, the source winding is the one that is directly connected to the source voltage. This winding receives the input voltage and plays a crucial role in the voltage regulation process. By being connected to the power source, it allows the regulator to accurately sense the voltage level and make adjustments as necessary to maintain consistent output voltage.

The other windings mentioned have different purposes. The induced winding typically generates a voltage based on the magnetic field changes in the core, while the shunt winding is connected in parallel with the load to provide feedback for voltage adjustment. The regulating winding is responsible for adjusting the output voltage of the regulator based on the feedback it receives. However, it does not connect directly to the source voltage. Therefore, identifying the source winding as the one connected to the source voltage is critical for understanding how voltage regulators maintain stable output voltages.
