Description

This component implements a modular multilevel converter (MMC) valve with full bridge submodules (FBSMs). The MMC consists of multiple FBSMs connected in series and an arm inductor. The individual FBSM consists of a capacitor and four switches.

The converter is modelled with a detail switch that is driven by a PWM generator with 0 or 1 signals.

To appropriately simulate the blocked state (diode mode), the "Activate iterative method" must be enabled in the Simulation Settings.
