It is important for machine design engineers to understand how transformers work so they can design machinery that operates optimally within the proper voltage ranges, as well as select the right ...

Designing flyback transformers for switch-mode power supplies involves many calculations. A spreadsheet can make short work of this otherwise-tedious task. When you develop flyback power supplies, ...

Growing data center power demands are driving server end-equipment manufacturers to reach higher power-conversion efficiencies in order to reduce the thermal footprint of their systems. The transition ...

I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...

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 ...

When alternating current (AC) prevailed over direct current (DC) in the late 1800s, one of the deciding factors was the need for voltage levels to be raised and lowered throughout the power system to ...
