Transformerless Power Supply Circuit We will use a zener diode among other elements to acheive the Transformerless Power Supply circuit. This means that our power supply will give a limited range current value (it will be a maximum and a minimum posible current that the power supply circuit can deliver). This power suply must be permanently connected to the circuit as a whole unit. […]
The transformer transformation ratio or transformer turns ratio (K) is the quotient value obtained by dividing the number of turns of the primary winding (N1) and the number of turns of the secondary winding (N2). Then K = N1/N2

Electric Power Transformer Structure
All electric transformers regardless of their size, have three fundamentals parts: high voltage winding, low voltage winding and the Core:
