A stepdown voltage converter of a kilowatt-class power plant based on fuel cells for an unmanned aerial vehicle is considered. A converter-replacement scheme is proposed that takes into account electrical processes in the fuel-cell stack, eddy currents in conducting structures, and parasitic inductances. A comparative analysis of the operating modes of converters with different circuitry is performed. A scheme of a stepdown transformer-free three-phase voltage converter with a common three-phase choke is proposed. It is shown that, in contrast to the classical schemes for the proposed three-phase converter circuit with one choke, the inductance and the choke mass can be significantly reduced almost without reduction in the quality of the converter, which will reduce the weight and dimensions of the structure, as well as the energy loss in the choke.
