Electrical energy is supplied by the grid as AC, yet most devices that we use require DC power, meaning that AC/DC power supplies that make this conversion are one of the most common loads placed on ...

The D2U5T-H3-7000-54 is a 3-phase AC-DC power supply with 95% efficiency. It provides a 7,000 W, 54 VDC main output, and a 5V or 3.3 V (20 W) selectable standby output. The device can operate in ...

While front-end ac-dc converters have changed significantly in terms of efficiency, density, and regulations, power factor issues continue to encumber the users of these supplies. It affects the ac ...

The study’s first author LIU Shiqiang explains the device’s characteristics: “Its superior ‘voltage ratio’ means it can efficiently interface with a wide range of energy sources, while the ...

Current regulations IEC-1000-3-2 impose strict requirements on the harmonic current content, which can be sent back to utility lines for all consumer electronic devices consuming more than 75W of ...

Hardly a day goes by without news of another billion-dollar hyperscale data center or utility-scale solar farm. Add in the ...

Green point-of-load DC-DC converter designs need high efficiency and low IQ, so what is the optimal POL converter for embedded systems. Most embedded systems are powered via a 48V backplane. This ...

A new DC-DC power converter is superior to previous designs and paves the way for more efficient, reliable and sustainable energy storage and conversion solutions. The development can efficiently ...
