The communications and computer industries initially used isolated converters in electronic industrial equipment, but as FPGAs required lower and lower voltages at higher currents, their power ...

Foster Transformer introduces a new line of Auto-Transformers or autoformers that use a single non-isolated winding to step up or step down the available line voltage to match the requirements of the ...

This document is an engineering prototype report describing a non-isolated -12 V, 250mA power supply utilizing a LNK305P. The design is a non-isolated buck-boost (inverting) topology. The input ...

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 ...

An autotransformer is a transformer having part of its winding included in both the input and output circuit. A simple autotransformer connection is shown in Fig. 1. Note that because there is a ...

Since 1987, MCEER, formerly the Multidisciplinary Center for Earthquake Engineering Research (MCEER) and the National Center for Earthquake Engineering Research ( NCEER), has produced over 600 ...

STMicroelectronics has created a 5W dc-dc buck converter IC that produces a regulated non-isolated output plus one or more transformer-coupled isolated outputs. The isolated secondary voltage is ...
