AC Direct DC Enabler This is a miniature, single silicon-chip–based AC/DC power converter with a topology that is neither a linear switch nor a switch-mode power supply. It’s a novel method for power ...

The Soft Power Switch is a passive, hard on/off switch with software feedback and control. In other words, it's like the on/off switch on a laptop. A simple press will turn the system on. Another ...

This paper presents a high step-down tranformerless single-stage single-switch ac/dc converter suitable for universal line applications (90-270 V rms) . The topology integrates a buck-type ...
