The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load.

Light flicker inside a building is usually associated with loose wiring, faulty switches, or poor electrical connections. But there are many situations in which lights flicker even when the ...

Switch-mode power supplies (SMPS) like dc-dc converters provide their best efficiency with heavier loads. When a device using a dc-dc converter goes into standby mode, efficiency drops considerable.

When the lights in your home start to flutter, your first instinct is usually to blame the bulb. Sometimes that is all you are dealing with, but persistent or widespread flicker often points to deeper ...

This file type includes high-resolution graphics and schematics when applicable. Low-power applications such as e-meters (electricity or energy meters) often require a simple ac line-powered supply ...
