Regenerative Power Supply
Addresses Efficiency, Safety, and Operation Costs
The consumer demand for electric vehicles (EVs) and hybrid electric vehicles (HEVs) continues to accelerate. Vehicle electrification in the automotive market brings with it new challenges in design and manufacturing. Consumers are looking for cars with a long-range, which means higher capacity batteries along with high-power electronics and chargers. Several newly designed EVs are using 800 V battery packs and chargers.
Using higher voltage chargers and batteries reduces the current required to deliver the same amount of power. 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. The Keysight RP7900 Series regenerative power supply can source and sink up to 20 kW of power with an output of up to 2,000 V using a single supply. When testing energy storage systems, it is essential to switch between sourcing and sinking current.
