A Step Up/Down Power-Factor-Correction Converter with Modified Dual Loop Control

Modified Bi-directional AC/DC Power Converter with Power Factor Correction

Most existing power  converters and industrial motor drive systems draw non-sinusoidal currents from the supply. Non-sinusoidal currents contained harm harmonics disturb the power supply which it causes serious concern for reliability. Other equipments that use the same power supply are adversely affected. This paper suggests the operation and performance of a new modified AC/DC converter that ...

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 ...

A Variable Switching Frequency with Boost Power Factor Correction Converter

This paper presents single phase Power Factor Correction (PFC) with proposed variable switching frequency (VSF) control technique. The increasing of non linear loads such as thyristor rectifiers, switching-mode power supplies, adjustable speed drives, and generate harmonic currents causing various problems to the other equipment connected to the point of common coupling. There are several disad...

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...
