Keysight RP7933A Bidirectional/Regenerative Power System

Overview

The Keysight RP7933A is a bidirectional regenerative DC power system delivering 20V at ±800A with 10kW maximum power output. It operates seamlessly as both a power source and regenerative electronic load, enabling continuous testing of energy storage systems and power converters. Unlike traditional power supplies that convert consumed energy to heat, the RP7933A returns 90% of the energy back to the grid, eliminating costly cooling requirements.

Key Features

• Output: 20V, ±800A, 10kW with two-quadrant sourcing and sinking capability
• Regenerates 90% of power back to the grid, reducing energy and cooling costs
• Sub-millisecond command processing for rapid transient response
• Seamless transitions between source and load modes without output disruption
• Battery emulation mode for realistic device characterization
• Supports up to 200kW through parallel connection of multiple units
• Integrated high-accuracy voltage and current measurement
• Compact 3U-high form factor with standard GPIB, USB, and Ethernet/LAN connectivity

Applications

• Hybrid and electric vehicle (HEV/EV) power converter testing and validation
• Energy storage and battery system development and characterization
• DC-DC converter and power electronics testing
• Battery emulation for device reliability and durability testing
• Grid interface and power quality applications
