“They don’t build ’em like they used to.” There’s plenty of truth to that old saw, especially when a switch-mode power supply from the 1940s still works with its original part ...

Power supplies are electrical devices that deliver electric power to one or several loads. They generate the output power by converting an input signal into an output signal. Switching power supplies ...

From there, zero-crossing detection is added to limit inrush surge currents, and the final design uses the venerable 555 timer to build a switching power supply. Although it is noted several times ...

Depending on the specific application, a designer can choose either a linear regulator (LR) or a switching mode power supply (SMPS) solution. To make the best choice of a solution, it is essential for ...

a USB Type-C PD power adapter can be used as a power supply with the option of selecting different output voltages via DIP switches. It is based on the cheap and easy-to-use CH224K multi fast charging ...

This USB-C to DC adapter utilizes the USB Power Delivery protocol that turns your USB-PD charger into a programmable power supply. Voltage regulation is done in the USB-PD capable charger, while this ...

However, there is still no power supply available that can actually do this. The first device of this kind could be the Delta ADP-240KB BA: It has already appeared at some distributors ...

I built microcontroller based( arduino nano) solar battery charger unit. I added the schematic ... But I can read stable current fo rinput. I change power supply's voltage but there is no change in ...
