As more electrically-powered devices are connected to the grid, the increased distortion to the electric grid can create problems in the electrical distribution network. So, power supply designs ...

Experienced designers know that for many system scenarios—even as disparate as a data link versus a power supply—one of the biggest challenges is getting the function to initialize and start up ...

Researchers develop a sensorless boost PFC method delivering near 0.9998 power factor and low distortion, enabling smaller and more reliable power supplies for consumer electronics. Single-phase power ...

This application note presents a numerical algorithm for IGBTs that operate in switch mode power circuits in order to determine its losses. The design example uses a 600 W zero-current switching boost ...

Electronic ballasts for fluorescent lighting deliver high efficiency and long lamp lifetimes. A new and simplified control circuit demonstrates complete control of the ballast, including all necessary ...
