The world’s first turnkey Modular Multilevel Converter test bench for labs.

Research into innovative HVDC interconnections and FACTS applications requires a flexible hardware architecture that allows testing of new topologies and switch configurations.

The OP1200 Modular Multilevel Converter (MMC) is the ideal test bench for the verification and prototyping of new control algorithms and for developing future HVDC interconnections.

The converter is ready to be connected to the power amplifier or to the electrical network and allows you to concentrate your efforts on innovation, not construction! This modular, but turnkey approach, lets you perform rapid control prototyping (RCP) of novel power electronics converters on actual hardware, making it perfect for:

  • High voltage DC (HVDC) converters
  • Flexible AC transmission systems (FACTS)
  • Static Synchronous Compensators (STATCOM)
  • Solid State Transformers
  • Power Amplifiers
  • Multilevel Matrix Converters

  • The OP1200 can also be used as a four(4) quadrant amplifier for PHIL (Power-Hardware-In-the-Loop) applications such as a motor emulator or power grid emulator as a means of implementing a full micro-grid analogue test bench.

    Modular, Flexible, and Configurable

    The OP1200 system chassis accepts ten (10) H-Bridge sub-module switches that support full and half-arm configurations. By directly wiring cells and submodules together user can form new HVDC and FACTS topologies and benefit from greater flexibility. Submodules are also equipped with a filter interface (common and differential modes), protection (Thyristor) and the possibility to add an additional IGBT switch for AAC topology.


    Specify the desired type of converter, the topology, the number of levels, the DC Voltage, the frequency and the output power and we will configure the Test Bench and deliver it, ready to use.

    By interfacing the converter with the OP4510 simulator hardware through its 6 optical link expansion board, user can prototype new control algorithms, drive amplifiers emulating the behavior of a real power system network, send firing command and receive measurement in real-time such as cell DC voltages and half arm currents. The OP4510 is also compatible with RT-LAB, MATLAB, Simulink, HYPERSIM, RTW, and Xilinx System Generator.

    Easy-to-Use Courseware

    The OP1200 comes with built-in models designed for use in an educational or training course. Using the complete software simulation environment RT-LAB MATLAB/Simulink® and XILINX System Generator, this turnkey test bench is safe, easy-to-use and ideal for teaching and control development of Modular Multilevel Converter systems.
