Abstract
- This paper describes a power-factor-corrected-based flyback converter for low-power domestic lighting. The proposed flyback converter works in a discontinuous-conduction mode (DCM) and provides enhanced power-quality (PQ). In low-power residential lighting, the flyback converter is significantly preferred over non-isolated converters owing to its numerous advantages, such as its low component count, cost-effective solution, and safe operating conditions. The proposed DCM-based flyback converter has a simple circuit configuration and lower total harmonic distortions (THD) of input current by about 15% with an input power factor of around 0.97. A hardware prototype has been developed and examined at different AC source voltages to validate the feasibility and effectiveness of a proposed model. Experimental results show that the whole system efficiency satisfies Energy Star standards with 91.04 percent efficiency at a rated load of 24 Watts and 220 V AC mains and also fulfilled the stringent limits as per IEC61000-3-2 Class D standards.
