• OP1210 MMC User Interface

The OP1210 is a sub-module unit that houses 10 sub-modules to create an MMC arm. It can be configured in the standard half-bridge or the optional full-bridge topology.

The user has three options when using the sub-modules in the OP1210 (see OP1210 Submodule Options). The first two options are software-controlled, using the model, and the third option is hardware-controlled and must be specified at the time of purchase:

Use the sub-modules as:

• full-bridge cells (FB), which means there are 4 active switches (2 half-bridge). 
• “emulated” half-bridge cells (HB): 2 switches are active and the 2 others are disabled in the software (switch state is forced to make a half-bridge cell topology). 
• “hardware” half-bridge cells (HB): a jumper is used to make to bypass the second half-bridge (must be factory configured).
