High-Efficient Electrolytic-Capacitor-Less Offline LED Driver With Reduced Power Processing

In this article, an integrated parallel buck-boost and boost converter (IPB 3 C) is proposed as an electrolytic-capacitor-less light-emitting diode (LED) driver. The IPB 3 C provides a high power factor (PF) and low total harmonic distortion (THD). The driver is composed of two converters that are c...
