Keysight Technologies RP7900 Series regenerative power supplies

Keysight Technologies is expanding its RP7900 Series with two bidirectional, regenerative DC power supplies providing integrated safety features that protect people and devices under test (DUT).

The series is part of Keysight’s HEV/EV Power Converter Test Solutions, which enable customers to deploy high-voltage, high-power solutions that meet the fast-paced, high-growth demands of the hybrid-electric/electric vehicle (HEV/EV) market. The regenerative design of the latest models enables the energy normally consumed to be returned to the grid cleanly, saving costs associated with energy consumption and cooling.

The power supplies — 20 kW and up to 2000 V per instrument — feature a two-quadrant, bidirectional sourcing and sinking capability that allows for seamless, uninterrupted transitions between sourcing and sinking current, without changing the power supply’s output characteristics or introducing any disruptive behaviour. An autoranging output characteristic should meanwhile improve flexibility over rectangular, or traditional, output characteristic power supplies due to an expanded power curve, which delivers more voltage and current combinations in one power supply.
