This paper deals with the question about the most efficient and less energy consumptive type of low voltage DC-DC converter in terms of low-voltage implementation. Different examples of such converter implementation are examined - for example, low voltage DC-DC converter can be used as power converter in photovoltaic system, or, for example, as charging converter for batteries, that are used, for example, in powered wheelchair. Three converter topologies (Čuk, Zeta and SEPIC) were examined in order to find out, which topology, with the same working frequency, passive component nominal values and semiconductor devices is more efficient. The comparison of output power of the converters is given.
