Abstract
Amplitude mode LEDs light regulation is most functional when LEDs are supplied from current fed buck drivers, which practical implementation is conjunction of non-inverting buck-boost circuit, extra coil and specific control methods. This report experimentally evaluates the efficiency of driver´s versions making focus on their losses and possible electric power savings.
