Summary:This paper presents a single-stage power factor corrected (PFC) converter for driving a solid-state lighting (SSL) device through light-emitting diode (LED) for street lighting use. The converter is based on CIC-CPPFC (continuous input current charge-pump power factor correction) technique, achieving continuous input current with high power factor and reduced current ripple by means of a coupled inductor. The converter operates with zero voltage switching (ZVS) resulting in high efficiency for a wide load range. It is also a cost effective and competitive solution for low power applications, such as SSL, where a two stage approach is costly and passive filters are not recommended. Another feature is the absence of a bulky dc-link capacitor, reducing costs, increasing life-time and presenting a significant advantage over many single-stage solutions.
