A double single-phase transformer consists of two single-phase transformers connected together to provide a three-phase power supply. Each single-phase transformer has a primary winding and a secondary winding.
In the diagram, there are two single-phase transformers labeled as T1 and T2. The primary windings of both transformers are connected in a delta configuration, while the secondary windings are connected in a star configuration. The primary windings are connected to the three-phase power supply, while the secondary windings are connected to the load.
When the three-phase power supply is connected to the primary windings of the transformers, a magnetic flux is induced in the core of each transformer. This flux induces a voltage in the secondary windings, which is then supplied to the load.
The double single-phase transformer operates on the principle of electromagnetic induction, where a changing magnetic field induces a voltage in a coil. By connecting two single-phase transformers together, a three-phase power supply can be provided to the load.
Overall, the double single-phase transformer allows for the conversion of a three-phase power supply to a single-phase power supply, providing flexibility in power distribution systems.

Principle of Operation:
A double single-phase transformer consists of two single-phase transformers connected in series or parallel. It is used to convert an AC voltage from one level to another with isolation between the primary and secondary windings.
1. Primary Windings: The primary windings (N1 and N2) are connected to the AC voltage source. When an alternating current flows through the primary windings, a magnetic field is created in the core.
2. Laminated Core: The core is made of laminated steel sheets to minimize eddy current losses. The magnetic field established in the core links the primary and secondary windings.
3. Secondary Windings: The secondary windings (N3 and N4) are electrically isolated from the primary windings. However, they are linked by the magnetic field created in the core.
4. Voltage Transformation: The number of turns in the primary and secondary windings determine the voltage transformation ratio. The ratio of secondary voltage (V2) to primary voltage (V1) is given by:
```
V2 / V1 = N3 / N1
```
5. Isolation: The physical isolation between the primary and secondary windings allows for voltage conversion with complete galvanic isolation, preventing leakage currents between the two circuits.
Operation in Series:
- When the single-phase transformers are connected in series, the secondary voltages add up, providing a higher secondary voltage.
- The primary voltages also add up, resulting in a higher primary voltage.
Operation in Parallel:
- When the single-phase transformers are connected in parallel, the secondary voltages are equal, but the currents add up, providing a higher secondary current.
- The primary voltages are also equal, leading to a higher primary current.
