I will explain about the SMPS switching transformer working concept. I will also discuss the core type, losses, Litz winding type, voltage and flux generation sequence, and reason for the small size and less weight of the SMPS transformer and differences from the power transformer.
I will also tell about using 1952 numbers of transformers used in one of our projects.

In this post I will explain, that why 30mA type RCCB breaker is used in the home and tripping time of the 30 mA RCCB. And if 30mA is not possible. Then how to use 300mA type RCCB breaker.
I will explain. where to use higher rating type RCCB breaker. Protection concept and as usual, I will share some extra knowledge as per my experience.
