4 FAQs about Regenerative Power Supply and Outdoor Power Supply

What is a regenerative DC power supply?

These power supplies, also known as regenerative DC power supplies, are designed to function both as a DC power source and a DC electronic load, providing efficient power management and minimizing heat dissipation.

Why are regenerative power supplies bi-directional?

Why Bi-directional? Regenerative power supplies and loads can pass power bi-directionally—both to and from the AC utility grid and a device under test. You may also hear these power supplies referred to as bi-directional.

Why do regenerative power supplies need to be charged and discharged?

These need to be charged and discharged to determine if they could be repurposed for other, less-demanding applications than automobiles. During the discharge phase of the testing, regenerative power supplies and loads can return that energy to the grid at efficiencies of up to 96 percent. This provides immediate economic benefits.

Why is a regenerative power supply important?

Lower currents mean thinner cables, which provide an added weight savings benefit to the vehicle. Manufacturers need safe, reliable hardware to test their high-power, high-voltage electronics. To meet industry needs, Keysight developed a regenerative two-quadrant power supply.
