The SilentSwitcher, A Quiet Mains-free Power Supply

Electronics News Updates / Ibrar Ayyub

What is it? The SilentSwitcher is a solution for powering your small-signal audio circuits with quiet, low noise and efficient power, totally separated from the mains. Audio projects are steadily getting smaller and the power supply with its transformer and rectifier and reservoir caps remain as large and looming as ever. I had been looking at

TORPEDO: an all-purpose switched-mode power supply

Electronics News Updates / Ibrar Ayyub

Having explained the theory, let’s see in practice the project of the SEPIC power supply. In this post we discussed – on a theoretical level (even if in a simplified way) – the SEPIC switching converters, also highlighting advantages and disadvantages, and giving you the basics for the calculation of their components. Let’s get

Op Amp Power Supplies: Split, Single, and Virtual Ground Designs

Electronics News Updates / Ibrar Ayyub

This is a great video of Alan Wolke talking about op-amp power supply options. He explains the differences when using op-amps on a single supply, a split (or bipolar) supply and virtual ground. This video discusses the power supply considerations for op amps. It talks about split or dual power supply and single supply operation,

Powering an Arduino Board from the Environment

News / Ibrar Ayyub

by Publitek European Editors: Building an Arduino system that harvests energy from the environment provides a significant amount of freedom from wiring, but requires some close attention to the system design. Using power from the environment and wireless links frees up the board from any wiring and gives tremendous flexibility for placing the equipment
