CORTEX Bidirectional Programmable DC Power Supply

High-Power Density and Compact 3U Form Factor

CORTEX is built on advanced power semiconductors and power electronics technologies. The architecture combines IGBT, SiC-MOSEFET, along with FPGA-based circuit and Digital Matrix Parallel control methods. From a 3U chassis where the maximum power rating offered is 30kW, test engineers can set up flexible in their test bench for laboratory testing applications thanks to the compact footprint and high-power density.

Source-Load Integrated Unit, Auto-Ranging and Automatic Switching

CORTEX DC combines regenerative programmable electronic load and high-precision programmable power source into one chassis. The bidirectional operation capability supplants the additional set of programmable electronic DC load for user cases where energy profile requires interaction of power flow while saving energy cost with 91% efficiency of regenerative recovery.

The auto-ranging and switching capability free test engineers from the conventional approach of setting operation mode in advance. The system conditions and regulates its operation automatically for voltage and current within its rated power and envelopes to fulfil maximum power output across various testing scenarios and uses cases dynamically and controlled. 

DMPS (Digital Matrix Parallel System) Technology for High-Power Scaling-Up

With 100 units of 3U/30kW chassis in parallel connection through DMPS technology, CORTEX DC allows flexible modular power up-scaling into standard racks by IEC-60297 for reaching 3 MW as the maximum power rating. High speed fiber-optic interconnection eliminates the latency among parallelled units, above which a further advanced feature of redundancy will isolate unit in fault from the parallelled system for maintaining the load current and consistent operation without downtime.

Versatile Output Modes Supported CC, CV, CP, CR and Precise and Flexible Programming

The Cortex DC series supports not only the basic Constant Voltage (CV) and Constant Current (CC) modes but also integrates Constant Power (CP) and Constant Resistance (CR) modes. The versatile operation mode is the control foundation to the simulation of both simple electronic components and complex power system.

Either from the integrated interface or from a host computer, test engineers can set up automated testing automation sequence combining miscellaneous current and voltage profiles following steps, list, advanced and custom modes, with an ultra-high measurement accuracy of 0.02% and an ultra-fast dynamic response as low as 500μs.

Integrated SAS (Solar Array Simulator) Mode, EN 50530 and Sandia Profile

SAS mode is optionally provided within CORTEX through built-in photovoltaic simulation software that fully complies with mainstream international standard models such as EN 50530 and Sandia which are critical functions for PV inverter testing.

Highlighted SAS mode features

• The system supports static I-V curve loading and dynamic curve programming. Users can perform static and dynamic MPPT (Maximum Power Point Tracking) efficiency tests.
• SAS mode can even simulate complex real-world weather changes and photovoltaic panel shading scenarios, making it an ideal choice for inverter R&D and certification testing.

Battery Simulator Mode with Versatile User-Defined and Settings

By integrating advanced software, CORTEX DC offers battery simulator mode that allows test engineers to set up a virtual and profile-controlled battery to replace a real one and achieve repeatable testing.

Highlighted battery simulator mode features

• Broad Range of Battery Types: CORTEX DC comes with built-in support for various mainstream chemical systems, including Lithium Manganese Oxide (LiMn2O4), Lithium Cobalt Oxide (LiCoO2), Lithium Iron Phosphate (LiFePO4), Nickel-Metal Hydride (NiMH), Ternary Lithium, and Lead-Acid batteries.
• Controlled Configuration and Customization: Users can flexibly set key parameters such as nominal voltage, internal resistance, capacity, and Depth of Discharge (DoD) according to their testing needs. By simulating the terminal voltage changes of batteries under different States of Charge (SoC), CORTEX helps engineers efficiently verify the performance of chargers, BMS (Battery Management Systems), and power tools without the need for physical batteries.
