Variable Transformer Diagram. Output voltage tolerance 1. This is the circuit diagram of the mobile phone charger.
A variable transformer is a type of transformer that can provide a variable secondary voltage from the same primary voltage. But how switch mode power supply works. The main supply of 220v is fed directly to the centre tapped transformer.
Linear variable differential transformers lvdts are differential transformer devices that have movable cores fig.
Its similar to the previous case. This commoned connection is the ve supply to the circuit. If you are using a cenrre tap transformer use 2 individual rectifer diodes thus. Power supplies made from these blocks are described below with a circuit diagram and a graph of their output.
