Microcontroller–Based Modified SEPIC Converter for Driving Lamp with Power Factor Correction

A methodological study of electronic ballast for electrode less lamps including design and development issues is presented in this paper. The ballast is intended to feed a 300 W ultra violet lamp at 100 kHz with dimming feature. The proposed topology is composed of a Single-Ended Primary Inductance Converter (SEPIC), used as power factor correction (PFC) stage, integrated with a resonant half-b...

Single-Inductor Dual-Output Buck-Boost Power Factor Correction Converter

In this paper a single-inductor dual-output (SIDO) buck-boost PFC converter operating in critical conduction mode (CRM) is proposed. By multiplexing a single inductor, each output of SIDO buck-boost converter can be regulated independently. Compared with conventional two-stage multiple output converter, SIDO buck-boost PFC converter benefits from significant overall cost saving, small size and ...

Bifurcation Behavior of a Power-Factor-Correction Boost converter

The aim of the paper is to investigate the bifurcation behavior of the power-factor-correction (PFC) boost converter under a conventional peak current-mode control. The converter is operated in continuous-conduction mode. The bifurcation analysis performed by computer simulations reveals interesting effects of variation of some chosen parameters on the stability of the converter. The results ar...
