Fault-Tolerant Method to Reduce Voltage Stress of Submodules in Postfault Condition for Regenerative MMC-Based Drive

Saleh Farzamkia et al.

Summary: The article proposes a fault-tolerant strategy for recovering the performance of a modular multilevel converter under submodule fault conditions by compensating for missing capacity with healthy submodules. The method reduces voltage stress on switches in postfault conditions and ensures homogeneous distribution of losses and temperatures in all parts of the converter. The proposed method enhances fault-tolerant capability without adding cost or complexity to the system.

A Software-Based Fault-Tolerant Strategy for Modular Multilevel Converter Using DC Bus Voltage Control

Saleh Farzamkia et al.

Summary: The article proposes a software-based method to enhance the fault-tolerant capability of modular multilevel converters (MMCs) by controlling the DC bus voltage. The method maintains larger line-to-line voltage in various fault states and balances the line-to-neutral voltages of the MMC in the postfault condition. Additionally, it addresses common-mode voltage, power-factor limitations, and electromagnetic interference issues seen in previous works.
