Abstract: The results of comparison of resonant LLC- and LCCconverters in the output voltage stabilization mode are presented. It is shown that in the LLC-converter, the regulation occurs due to the parametric phase shift of the shunt choke current, that allows minimizing the inverter current. In the same time in the LCC-converter, the regulation is carried out exclusively due to the introduction of a recuperation interval, overestimating the losses. An assessment of the effective value of the inverter current is carried out, it is found that the maximum static losses are the same for both converters, the difference is that they correspond to different points of the regulation range.
