Independent of their individual topology and application, due to AC components in their lines switching controllers create conducted EMC interferences. Würth Elektronik MagI³C power modules are ...

Prior knowledge needed: ECEA 5700 Introduction to Power Electronics, ECEA 5701 Converter Circuits, ECEA 5702 Converter Control, ECEA 5703 Magnetics Design, ECEA 5705 Averaged Switch Modeling and ...

Ericsson POL regulators are implemented by using non-isolated synchronous buck topology shown in Figure 1. During normal operation of a buck power stage, QH and QL are alternatively switched on and ...

The following are some basic facts about input loop power sources: The input module usually isn't a loop power source. Although 120V is common for digital loops, other voltages are also used. There ...

Switched mode inverters and converters form the heart of many modern power applications including ‘smart’ motor drives, solar power, UPS systems, high power AC-DC converters and many more. All these ...

Filter modules with built-in transformers offer 10G designers a wealth of design and performance-enhancing options. In June 2006, the IEEE committee ratified the 10GBaseT specification (IEEE 802.3an) ...

In our previous issue, we noted that the first step in troubleshooting digital input modules is to verify the power source of each loop. If input power is missing, the causes can be such things as ...
