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 conduction, commutation and inductor losses.
