Single-ended primary inductor converter (SEPIC) for LED application
This paper focuses on the design of a capacitor diode (CD) resistor-less snubber that is able to reduce the power loss with improved efficiency for a MOSFET switch in a single-ended primary-inductor converter (SEPIC) for LED application. There are many types of snubber circuit available in the liter...

This paper focuses on the design of a capacitor diode (CD) resistor-less snubber that is able to reduce the power loss with improved efficiency for a MOSFET switch in a single-ended primary-inductor converter (SEPIC) for LED application. There are many types of snubber circuit available in the literature; however, the basic concept literally consists of inductor, capacitor, resistor and diode. The conventional method that includes a resistor should be avoided since it promotes a higher loss in the converter. Among the most used topology for LED driver is the single-ended primary-inductor converter (SEPIC). This topology has efficiency up to 90%, small in size and weight.
