研究目的
Investigating the design and performance of a three-leg interleaved boost Power Factor Corrector (IBPFC) converter for high-power LED lighting applications connected to the main grid.
研究成果
The three-leg IBPFC converter demonstrated satisfactory performance in terms of efficiency, power factor, and THD within the 1-3 kW power range. The novel inductance design methodology ensured CCM operation, and the use of IGBT devices provided a cost-effective solution. Future work includes engineering the prototype for complete AC/DC and DC/DC driving systems for high-power LED lighting.
研究不足
The complexity of the control circuit increases with the number of boost legs in parallel. The study is limited to a 3kW prototype and may require further validation for higher power applications.
