Power Supply Unit (PSU) is a vital part in any electronic product design. Most household electronic products like Mobile Chargers, Bluetooth Speakers, Power Banks, Smart Watches etc requires a Power ...

The objective of this project is to convert 220V AC supply in to +12V and -12v DC supply, that is why it is named Dual Power Supply as we get positive and negative 12v power supply at the same time.

This mini ups circuit provides an uninterrupted power supply (UPS) to operate 12V, 9V and 5V DC-powered instruments at up to 1A current. The backup battery takes up the load without spikes or delay ...

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...

Op-amps require dual-polarity supply for proper operation. When working with battery supply, it becomes difficult to get dual power supply for the op-amps. Presented here is a simple circuit that ...

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 ...

SCRs are the switching devices for this unusual DC to DC converter that is suited for the ubiquitous 5V USB power source as well as numerous other applications. This novel power circuit topology uses ...

AutomationDirect offers switching power supplies at linear supply prices. We offer some of the most practical industrial control power supplies available. PS series, PSP series and PSM series power ...

Abstract: This article presents the design and experiment of a multi-output DC supply for a 5G millimeter-wave front-end module, with some specified requirements, such as miniaturization of power ...
