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.

A Low THD Three-Level Rectifier For Gen-Set Applications

IEEE Transactions on Industry Applications, 2019
A low input current total harmonic distortion (THD) rectifier is presented, tailored around an open-end winding permanent magnet synchronous generator. Specifically, a six-level converter topology is obtained by connecting the generator stator winding to a three level T-type unidirectional rectifier on one side, and to an auxiliary two-level inverter ...

High-PF and ultra-low-THD power factor correction controller by sinusoidal-wave synthesis and optimized THD control

2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013
The proposed sinusoidal-wave synthesis (SWS) and the optimized THD control (OTC) improve power factor (PF) and total harmonic distortion (THD) over a wide line voltage range. The SWS detects the input line root-mean-square (rms) voltage to generate the digital equivalent code to the OTC for optimizing the THD by tuning the on-time value.

Diode Bridge Rectifier with low THD for Weak Grids

2019 IEEE Transportation Electrification Conference (ITEC-India), 2019
Diode bridge rectifiers are simple means of converting single phase AC to DC. Such converters are widely used in many applications primarily in low cost and low to medium power ranges. Large transportation systems such as ships are operated as microgrids with a variety of loads some of which need rectification.

An improved "charge pump" electronic ballast with low THD and low crest factor

IEEE Transactions on Power Electronics, 1997
The "charge pump" electronic ballast circuit, which employs a charging capacitor and a high frequency AC source to implement power factor correction (PFC), has become an attractive topology for ballasting fluorescent lamps because it eliminates the use of a bulky boost inductor.

A Class D amplifier output stage with low THD and high PSRR

2009 IEEE International Symposium on Circuits and Systems, 2009
This paper presents a Class D amplifier output stage with low Total Harmonic Distortion (THD) and high Power Supply Rejection Ratio (PSRR). The Class D output stage reduces the non-linearities and supply noise by means of a second-order negative feedback loop embodying a single stage second-order integrator and a Schmitt trigger comparator.
