Last month's Code Calculations article covered transformer calculation definitions and some specifics of delta transformer calculations. This month we turn our attention to the differences between ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

Fig 1. Designers can parallel identical fixed-ratio isolated bus converters to create the high-power array in an intermediate bus architecture. Fig 2. This array of identical fixed-ratio isolated bus ...

Many older industrial facilities use single-phase, oil-filled transformers made for pole-mounting but installed at ground level to create 3-phase power distribution systems. Usually, primary and ...

Several switching-converter topologies exist for power converters that operate from the ac mains and must maintain a power factor of 0.9 or better. One topology is a boost converter with a control ...

Find a downloadable version of this story in pdf format at the end of the story. Until now, it was considered impossible to have an AC-DC converter with PFC and isolation features provided in a single ...
