This circuit is a small +5V power supply, which is useful when experimenting with digital electronics. Small inexpensive wall transformers with variable output voltage are available from any ...

The circuit drawn pertains to a regular industrial UPS (Uninterruptible Power Supply), which shows how the batteries take control during an outage in electrical supply or variation beyond the normal ...

Learn how to select a power-supply configuration based on PPG system requirements. Review the implementation of switched-mode power-supply reference circuits for both discrete (part one) and ...

How semi-automated tools speed up the power-supply design process. The five main steps to take when building a power-supply architecture. How do LTpowerPlanner and LTspice help facilitate the ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...

The PC power supply has been a standard of the junk box for the last couple of decades, and will probably continue to be for the foreseeable future. A product that is often built to a very high ...

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 ...

STMicroelectronics is aiming at industrial and telecom power supplies with half-bridge driver for GaN power transistors. With a maximum rail voltage of 220V, STDRIVEG211, as it will be known, is ...

We are sometimes asked our opinion of exotic power cords, and have met more than a few people who have laid out some serious investment to have what they see as the very best sort of cord running from ...
