This paper proposes a light-emitting diode (LED) driver based on a three-phase resonant switched capacitor (SC) converter. The LED lamp employs chip-on-board (COB) technology, as it is possible to achieve high power density. The three-phase structure provides low ripple current and reduced percent f...
