MMC Valve (HB Cells)


Description

This component implements a modular multilevel converter (MMC) valve with half-bridge submodules (HBSMs). The MMC consists of multiple HBSMs connected in series and an arm inductor. The individual HBSM consists of a capacitor and two 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.
