Your gadgets run on direct current, but the electricity in your home is alternating current. What’s up with that?

Mastering the nuances of modern ac-dc power supply selection ...

1. Shown is a simplified block diagram of the MCP39F511A. The MCP39F511A includes an asynchronous full-duplex UART with eight Start and Stop bits and a default baud rate of 9.6 kb/s. The Simple ...

Left panel, superconducting rectifier circuit used to convert AC currents into DC using four superconducting diodes (blue) connected by superconducting interconnects and one smoothing capacitor (C ...

This gives the DC current from batteries several advantages over AC power, including its reliability, as it mitigates the effects of power outages and acts as a ready supply of power.
