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.
