Auto Transformer Circuit Diagram. The voltage at rated frequency is applied to that lv side with the help of a variac of variable ratio auto transformer. We can convert the high voltage ac into low voltage such as 5v 6v 9v 12v dc without using the transformer which is called transformerless power supply.
This winding is tapped from point c and the portion bc is considered as secondary. Circuit diagram of short circuit test on transformer. A step down transformer having secondary volta ge suited to the.
Before going straight into building the prototype part let s explore the 5v 2a smps circuit diagram and its operation.
We can convert the high voltage ac into low voltage such as 5v 6v 9v 12v dc without using the transformer which is called transformerless power supply. The generator 1 voltage is connected to l1 l3 via protection fuses 4. The generator circuit breaker is driven by the digital output 2. The winding ab of total turns n 1 is considered as primary winding.
