The OP1200 Modular Multilevel Converter is a test bench dedicated to the verification and prototyping of new control algorithms for the development of multilevel HVDC interconnections. It consists of a stack of cascaded identical or mixed-topology sub-modules (SM) composing up to 60 switching cells (in the standard configuration). 

The OP1200 comes with built-in models designed for use in research or educational or training courses.

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 implementing (and teaching) control development of Modular Multilevel Converter systems.
