Solid-state switch-mode rectification converters have reached a matured level for improving
power quality in terms of power-factor correction (PFC), reduced total harmonic distortion at …

We introduce quaternionic Gabor filters for the classification of local image structure. These
filters are constructed as windowed basis functions of the quaternionic Fourier transform. We …

In this paper an analysis and design of a dimming control based on sliding mode control
(SMC) strategy for electronic ballast (without resonant tank) is presented. The lamp current is …

This paper presents a dynamic model for HID lamps; the model is based on thermal and
electric principles. The model considers that the conductivity of the plasma inside the lamp …

In this paper a new topology of a voltage regulator with high power factor and improved
efficiency is presented. Traditional topologies correct the power factor processing twice the …

In this paper a high power factor pre-regulator with high efficiency is presented. In the
proposed scheme one converter is used, but it does not process all the power delivered to …
