Power supply design has traditionally placed a high priority on energy efficiency. The system and the end user will pay more if the power supply is inefficient and has non-negligible power losses. Let ...

Bill Traue, CSRE, 8-VSB, AMD is principal of Bill Traue Technical Services. He acknowledges that when it comes to fixing dead switched-mode power supplies, the small wall-wart or line-lump type aren’t ...

Both switching and linear regulators in power supplies carry out the identical task of producing a regulated output voltage from an uncontrolled input voltage. However, they carry out this duty using ...

Learn more about integrating GaN power FETs into switch-mode power supplies and what you must change when upgrading from silicon MOSFETs. The power-handling properties of GaN. The unique challenges of ...

Methods for mitigating noise in SMPS. Creating lower-noise designs. Challenges encountered with conducted emissions and meeting emissions standards. Power designers in search of high power efficiency ...

Perhaps the simplest way to regulate a DC voltage is using a voltage divider and/or an active device like a Zener diode. Besides simplicity, they have the additional advantage of not being ...

The power supply is often the first component to fail in broadcast equipment, whether due to line surges, overheating or component aging. A client of Frank Hertel had a console with an internal switch ...
