Posted in: IEEE 2017, Power System
Front-End Converter With Integrated PFC and DC–DC Functions for a Fuel Cell UPS With DSP-Based Control Abstract: This paper presents the development of a boost converter with integrated power factor correction (PFC) and dc-dc functions for a proton exchange membrane fuel cell (PEMFC) uninterruptable power supply (UPS). Through the use of a passive resonant soft-commutation […]

Comments Off on Offline Soft-Switched LED Driver Based on an Integrated Bridgeless Boost�Asymmetrical Half-Bridge Converter
Posted in: IEEE 2017, Power System
Offline Soft-Switched LED Driver Based on an Integrated Bridgeless Boost–Asymmetrical Half-Bridge Converter Abstract: This paper proposes an offline single-stage light-emitting diode (LED) driver based on a novel approach to reduce low-frequency ripple in LED arrays supplied from mains, while assuring high input power factor (PF). The proposal employs a series resonant dc-dc converter integrated into […]
