New Taipei City, Taiwan – [2025/10/01] – Good Will Instrument Co., Ltd. (GW Instek), a leading global supplier of electronic test and measurement instruments, proudly announces the release of the RBS Series Regenerative Bidirectional DC Source. Designed to meet the rigorous demands of the new energy sector, the RBS series offers a versatile, programmable solution with both power sourcing and absorption capabilities, advancing testing efficiency for energy conversion devices and energy storage components. 

Powering the Future of Energy Innovatio

The RBS series is purpose-built for the development and production testing of electric vehicles, energy storage systems, photovoltaic (PV) power generation systems, and charging modules. By supporting energy recovery and grid feedback, the RBS helps enterprises “implement ESG from the equipment selection stage” and integrate energy-saving indicators into sustainability reporting. 

Dual Functionality: Source and Load in One

Unlike traditional test setups that require both a DC power supply and an electronic load, the RBS series integrates both functions into a single compact system. Capable of feeding regenerative energy back into the grid, it eliminates the need for external diodes and dedicated loads, delivering:

• Simplified configuration

• Reduced system footprint

• Improved energy efficiency

This makes the RBS series an ideal solution for motor driver testing, especially in braking or downhill energy regeneration scenarios. 

Advanced Simulation Capabilities

The RBS series features standard SAS (EN50530, Sandia) and SAS2 functions with support for static and dynamic MPPT testing, enabling accurate simulation of solar irradiation conditions such as cloud movement and shading. For battery-related applications, the RBS incorporates nearly 10 built-in battery models based on internationally recognised research data, including:

• Lithium Manganate (LMO)

• Lithium Cobalt Oxide (LCO)

• Lithium Iron Phosphate (LFP)

• Ternary Lithium (NCM)

• Lithium Titanate (LTO)

• Lead-acid (Pb)

• Nickel-Metal Hydride (NiMH)

• Nickel-Cadmium (NiCd)

This versatility allows engineers to simulate real-world charging and discharging behaviours to validate energy storage systems under various conditions. 

Scalable Power for Diverse Applications

With a voltage output range up to 2250 V, current up to 510 A, and power density of 5/10/15 kW in only 3U height, the RBS series delivers robust performance in a compact form factor. Multiple units can be paralleled (up to 10 of the same model) for a maximum power capacity of 150 kW, providing flexibility for high-power testing scenarios.
