Description
Summary:This paper describes the design and implementation of a boost connected in cascade with a quadratic buck converter, with just one active switch, used to drive a LED string for public and private lighting purposes. The proposed converter supports a wide input voltage range that makes it possible to be supplied from 12 V DC to 340 V DC (240 V AC ), without any additional adjustment. It can be used in hybrid electrical systems supplied by photovoltaic systems or 110/220 V AC from the utility power grid. Experimental results from an 11 W prototype are also presented.
