KEY TOOLS AND SOLUTIONS

Building blocks for real-time innovation

The OP1210 H-Bridge submodule

The OP1200 solution includes six OP1210 submodule boxes, each containing 10 submodules configurable as full-bridge, emulated half-bridge, or hardwired half-bridge. Each OP1210 unit features built-in protections, including overvoltage, overcurrent, and overtemperature, to prevent damage and ensure reliable operation.

The OP4512 simulator platform

Interfacing the converter with the OP4512 simulator via its 6 optical link expansion board allows users to prototype new control algorithms and emulate real power system networks. Real-time measurements, such as cell DC voltages and half-arm currents, can be tested alongside firing commands. Learn more about the OP4512.

Solutions for the entire development V-Cycle

We provide Hardware-in-the-Loop (HIL) technologies to help engineers develop and test MMC control algorithms. Once validated through Rapid Control Prototyping (RCP), these algorithms can be further refined using the OP1200 test bench.
