Low THD variable load buck PFC converter

2008 IEEE Power Electronics Specialists Conference, 2008
International standards impose several constraints concerning the electric power quality and require that the harmonic content of the line current of grid connected equipment is below assigned limits; for this reason operating of ac-dc converters with high power factor and low line current distortion has become essential.

Bidirectional flyback inverter with low output voltage THD

2015 IEEE 10th Jubilee International Symposium on Applied Computational Intelligence and Informatics, 2015
This 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.

Fuzzy logic as a basis for a theory of hierarchical definability (THD)

33rd International Symposium on Multiple-Valued Logic, 2003. Proceedings., 2004
Attempts 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, 2008
Recent 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.
