THD Minimization and Reliability Analysis of Cascaded Multilevel Inverter
Journal of Circuits, Systems and Computers, 2023Inverters are DC to AC power converters that are widely used in AC motor drives and distributed energy generation systems. Multi-Level Inverters (MLIs) have emerged as the preferred inverter technology because of their advantages of reduced switching losses and better harmonic profile.

Bidirectional flyback inverter with low output voltage THD
2015 IEEE 10th Jubilee International Symposium on Applied Computational Intelligence and Informatics, 2015This paper develops a single-phase voltage source inverter mainly containing a high frequency flyback bidirectional DC-DC converter — as a previous stage, and a full-bridge module. The flyback bidirectional converter generates a rectified sinusoidal voltage waveform across the output capacitor.

Multiobjective optimization for Volt/Thd oroblem in distribution system
2014 Sixth World Congress on Nature and Biologically Inspired Computing (NaBIC 2014), 2014This paper deals with integrated voltage and harmonics distortion control (volt/THD) for radial distribution feeders in planning issues, by means of the application of automatic voltage regulators (AVRs) banks and harmonic passive filters. A multiobjective genetic algorithm (SPEA2) improved using fuzzy logic is presented to solve the VOLT/THD problem ...

Fuzzy logic as a basis for a theory of hierarchical definability (THD)
33rd International Symposium on Multiple-Valued Logic, 2003. Proceedings., 2004Attempts to formulate mathematically precise definitions of basic concepts such as causality, randomness and probability have a long history. The concept of hierarchical definability that is outlined in the following suggests that such definitions may not exist. Furthermore, it suggests that existing definitions of many basic concepts, among them those

A Hybrid A/D Converter with 120dB SNR and -125dB THD
2008 IEEE International Test Conference, 2008Recent 18 to 24 bit ADCs, especially for audio applications, require an excellent signal to noise ratio (SNR) performance and an excellent total harmonic distortion (THD) performance at the same time. Moreover, most of applications require precision DC performance.
