A High-Power-Factor Dimmable LED Driver with Integrated Boost Converter and Half-Bridge-Topology Converter
This paper proposes a dimmable light-emitting diode (LED) driver featuring a high power Top Mount factor and zero-voltage switching on (ZVS).The circuit is obtained by integrating a boost converter and a dc-dc converter with half-bridge topology.The high power factor is achieved by operating the boost converter in discontinuous current mode (DCM).T
