“…However, multilevel NPC topologies require the explicit design of a strategy for DC‐link capacitor voltage balance. Several solutions addressing this imbalance issue for NPC inverters have been recently reported in previous studies . Most of these solutions address the capacitor voltage balance by directly altering the modulation strategy design.…”

Summary In this paper, a controller for a shunt active power filter based on a 3‐level neutral point clamped inverter is presented. The proposed controller guarantees compensation of harmonic and reactive powers caused by nonlinear loads connected at the point of common coupling. The controller comprises three control loops, namely, a current tracking loop, a voltage regulation loop, and a voltage balance loop. The current tracking loop is aimed to inject the appropriate current by means of the power inverter to compensate reactive power and harmonic distortion assuring a power factor close to unity. The voltage regulation loop is designed to assure that the DC‐link reaches a desired constant voltage level, while the voltage balance loop is aimed to regulate each capacitor voltage on the DC‐link towards the same voltage value. The performance of the proposed controller is experimentally validated on a 1 kW prototype.

“…As an important part of energy conversion, cascaded H-bridge Multilevel Inverter (CHMI) is widely used in high power applications for medium and high voltages thanks to its high switching frequency, small number of components and low total harmonic distortion [2][3][4]. However, when its level increases, the reliability of the inverter will be reduced due to the eventual loss and faults of components [5,6].…”

A Principal Components Rearrangement Method for Feature Representation and Its Application to the Fault Diagnosis of CHMI

et al. 2017

Cascaded H-bridge Multilevel Inverter (CHMI) is widely used in industrial applications thanks to its many advantages. However, the reliability of a CHMI is decreased with the increase of its levels. Fault diagnosis techniques play a key role in ensuring the reliability of a CHMI. The performance of a fault diagnosis method depends on the characteristics of the extracted features. In practice, some extracted features may be very similar to ensure a good diagnosis performance at some H-bridges of CHMI. The situation becomes even worse in the presence of noise. To fix these problems, in this paper, signal denoising and data preprocessing techniques are firstly developed. Then, a Principal Components Rearrangement method (PCR) is proposed to represent the different features sufficiently distinct from each other. Finally, a PCR-based fault diagnosis strategy is designed. The performance of the proposed strategy is compared with other fault diagnosis strategies, based on a 7-level CHMI hardware platform.
