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 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 ...

Today, 80% of all input/output (I/O) devices in automation applications are supplied with 24VDC power. The second most popular voltage is 120VAC, which is used on 15% of all I/Os. Over the past decade ...

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 ...

This file type includes high resolution graphics and schematics when applicable. Switching power supplies are inevitable in today’s designs. They’re power-efficient and thermal-efficient, with various ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

Standard ATX power supplies aren't designed to turn on unless they are properly connected to a motherboard. This helps to ensure that they can't power up and damage computer components if the plug isn ...

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 ...

Most casual business users don't give a lot of thought to their computer's power supply unless they use a laptop and lose its AC adapter. However, desktop computer power supplies are crucial ...
