concentration presents a power distribution in the vertical shaft. The ventilation and aeration
scale effects of models are both obvious. Therefore, the use of an annular aerator is necessary to
set in the vertical shaft of gyrating discharge tunnel while satisfying the structural designs
demands, which can improve the flow pattern and increase the energy dissipation significantly.

Abstract: For utilizing energy availably, the system efficiency of distributing power supply
ought to be improved possibly; the system is composed of DC-DC converters with uniform or
different power grade. In this paper, the efficiency model of Buck converters in the continuous
conduction mode (CCM) was educed based on the average loss, and the calculation method of
parameters for the efficiency model was given. For optimizing the operation efficiency of the
