About two decades ago there was a quiet revolution in electronics which went unnoticed by many, but which overturned a hundred years of accepted practice. You’d have noticed it if you had a mobile ...

Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...

Design engineers are constantly faced with the challenge of specifying a transformer that will meet design specifications as well as cost constraints. The designer who draws up the circuit ...

The use of power electronics is increasing in the industry for both low-scale applications like chargers for batteries and LED drivers and high-scale applications like photovoltaic (PV) systems and ...

Transformers for power applications often are limited in size by an acceptable temperature rise. An acceptable temperature rise of a transformer is usually dependent on limitations of the materials ...
