Use a three-phase rectifier and voltage reducer for offline single-phase supplies
Jul 6, 2025 Circuits

Some industrial applications require you to feed a low-power dc/dc converter from a three-phase source and possibly to deal with line-to-line voltages of 200 or 400 V rms. Further, the neutral terminal of the ac source may be unavailable for connection...

ADC clock polarity vs. start-up time
ADC clock polarity vs. start-up time
Jul 2, 2025 Articles

High speed analog-to-digital converters are by definition devices that sample an analog signal and, as such, must have sample clock inputs. Some system designers that utilize ADCs have observed a slower than expected startup from the time the sample clock is initially applied...
