Switched-mode power supply - Wikipedia
A switched-mode power supply (switching-mode power supply, switch-mode power supply, switched power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains power) to DC loads, such as a personal computer, while converting
IC Voltage Regulators-with Circuit Diagram - Design & Theory
The figure above shows the application of LM340 IC as a voltage regulator. Pins 1, 2, and 3 are the input, output and ground. When there is quite a distance (in cms) from the IC to the filter capacitor of the unregulated power supply, there may occur unwanted oscillations within the IC due to lead inductances within the circuit.
Modifying a Chinese power supply to provide a variable voltage
After this page was posted on Hackaday, a commenter pointed out that 7 is actually a standard power supply voltage! I never knew this, so I was only searching for 5V, 12V, 24V supplies. Sure enough, there are lots of 7 supplies around - for example TRC Electronics addition, most of these will have ±5% adjustment so, for the original application which required 7, I could just have
Notes on the Troubleshooting and Repair of Small
Back to SMPS Repair FAQ Table of Contents. Switchmode Power Supply Troubleshooting SAFETY The primary danger to you is from the input side of the supply which is directly connected to the AC line and will have large electrolytic capacitors with 320 V or greater DC when powered (often, even if the supply does not work correctly) and for some time after being unplugged (especially if the power
