Making a dc voltage from an ac source means you will have to rectify the ac voltage to get a dc bus. One difference compared to a dc-dc converter is that you can use a linear power supply with an ac ...

Worldwide ac mains voltages can range from 100 to 240 V. To allow for sags (brownouts) and surges, offline ac supplies intended for universal input are rated at 85 to 165 V. The ac frequency ranges ...

AC/DC power supplies are used in several electronic devices, encompassing computers, smartphones, radios, and TVs. AC/DC power supplies come in many dimensions and configurations, tailored to suit the ...

DC motors come in many forms, but they all have the same job: turning electrical energy (DC) into mechanical energy. Although DC motors have a common operating principle, many applications—including ...

You may have seen the Ruideng range of programmable power supply modules from China: small and relatively inexpensive switch-mode buck converters, with microprocessor control and a front panel ...

A well-organised industrial network operates efficiently within every control panel. At the system's core is an AC-to-DC ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

Our recent article “10 power-saving myths debunked” generated a lot of interest and controversy. One topic that sparked plenty of discussion was the use of DC power in the data center. Because all ...
