The venerable ATX standard was developed in 1995 by Intel, as an attempt to standardize what had until then been a PC ecosystem formed around the IBM AT PC’s legacy. The preceding AT form factor was ...

Switched-mode power supplies are found in electronics all around us. They provide the DC voltages that power our computers, cell phones, chargers, appliances, and myriad other electronic devices.

The circuit of power supply for PC works with a mains voltage of 230VAC to produce an output of 13.8V at 5A due to rectification. This project came upon the modification of a PC switch mode power ...

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 ...

Power supply. This is perhaps the most critical part of any computer that still gets overlooked by many. But the thing is, a PC can always be built without a graphics card (assuming that you picked a ...

Economy of scale is a wonderful thing, take the switch-mode power supply as an example. Before the rise of the PC, a decent multi-voltage, high current power supply would be pretty expensive. But PCs ...

An uninterruptible power supply (UPS) offers a simple solution: it’s a battery in a box with enough capacity to run devices plugged in via its AC outlets for minutes to hours, depending on your needs ...

Ideally switch-mode power supplies would behave like mathematical models. But since they don’t you need to perform thorough characterization and troubleshooting. Fortunately, modern oscilloscopes are ...
