In this paper a new LED driver and its controller are conceived realized and experimentally validated. It presents several advantages compared with existing counterparts: First it uses a single converter while most of the existing drivers are based on a two-converter architecture. In the proposed approach the average current through the LED is directly regulated. The proposed driver is built ar...

For high-bay and outdoor lighting fixtures, the cost of LED driver electronics is reported to be 17 percent of the total fixture cost. An additional 40 percent of the fixture cost comes from the mechanical, thermal and electrical portions of the fixture [1]. These portions help support the weight and volume of the LED driver, as well as protect the driver against surge events, such as lightning...
