3-Phase Series Resonant Converter Based LED Driver without Rectifier stage

This paper proposes a 3-phase series resonant converter (SRC) based Light emitting diode (LED) driver. Input current ripple is reduced due to 3-phase operation of the converter. Advantage of the proposed driver is, LEDs are powered without Rectifier stage. Other advantages of the proposed LED driver include ZVS of the switches, less component count and high efficiency. A 40W LED driver is simulated in PSPICE. These type of converters are suitable for the LED lamps supplied through solar panels.
