Conference Paper
A promising solution for operations in the moderate voltage and high-power ranges, the Alternate Arm Multilevel Converter (AAMC) distinguishes itself with a distinctive topology as an AC-DC Voltage Source Converter (VSC). However, traditional implementations require numerous sensors to maintain capacitor voltage balancing across series Full-Bridge...
Conference Paper
The Nested Neutral Point Clamped (NNPC) converter, functioning as a voltage source Converter (VSC), provides an effective solution for applications requiring Medium-Voltage and High-Power (MVHP). Earlier implementations of this converter typically required many sensors to maintain capacitor voltages equally in all series Half-Bridge Sub-Modules (HB...
Article
In multilevel converters (MCs), system components such as capacitors and semiconductor switches are very susceptible to damage. Furthermore, utilizing voltage sensors to balance capacitor voltages increases the system’s cost and complexity while decreasing reliability. This paper presents methods for voltage balancing of capacitors, capacitance mon...

The modular multilevel converter (MMC) is a favored topology in the industry, but its reliability is at risk with an increase in the number of sub-modules (SMs) due to a rise in switching components. The essential need for maintaining capacitor voltage balance in each arm leads to increased complexity and cost, as numerous voltage sensors are requi...
Article
The modular multilevel converter (MMC) is an innovative structure that has expanded the usage of multilevel converters (MLCs) in the electrical industry. Since the MMC initially required a large number of sensors to manage the capacitor voltages, various studies have been done to reduce their number to improve the converter's reliability and reduce...
Conference Paper
The nested neutral point clamp (NNPC) converter is one of the most promising solutions for medium voltage motor drive applications. However, reliability due to the presence of semiconductor switches in the structure of this converter is one of the most critical concerns. The semiconductor switches are always one of the main components prone to fail...
Conference Paper
The alternate arm multilevel converter (AAMC) is a new type of voltage source converter topology introduced as an attractive option for medium voltage and high-power applications. In AAMC, many series full-bridge sub-modules (FB-SM) are used to achieve high-voltage applications. Despite this, a large number of voltage and current sensors are needed...

Multilevel converters (MLCs) are pioneers in the field of electrical energy conversion. From the classification of MLCs, modular multilevel converter (MMC) is very popular due to its attractive structure and performance. The modular nature and no need for isolated DC resources are two great advantages in this converter, but the need for many sensor...
Conference Paper
Recently, the nested neutral point clamped (NNPC) converter has been developed for medium voltage applications. This converter has been considered for its desirable properties, such as application in a wide range of voltages, the low voltage stress on the switches, and excellent output waveform quality. This study presents a fast open-circuit fault...
Conference Paper
The modular multilevel converter (MMC) is one of the most commonly used power electronic converters in medium and high-power applications. However, reliability is one of the most critical challenges because of the many power switching devices applied in the MMC. Also, many voltage sensors in the converter topology have increased cost and hardware c...
Conference Paper
Modular multilevel converters (MMCs) play an essential role in power conversion for medium and high voltage industrial applications. These types of converters use many sensors for the process of measuring and sorting the voltage of their capacitors, but this increases cost and hardware complexity, as well as decreases reliability. One of the most w...
Conference Paper
In this article, the combination of a new capacitor voltage sorting method and an open-loop control approach based on the energy estimation of the arms is used in the modular multilevel converters (MMCs). The presence of circulating current, the use of multiple voltage and current sensors, and the voltage imbalance of the capacitors increase the co...
