摘要：

Power electronics based zonal DC power distribution systems are being considered for sea and undersea vehicles. The stability of the DC power electronics based power distribution systems is a significant design consideration because of the potential for negative impedance induced instabilities. In this paper, dynamic properties land control of a buck converter feeding a downstream DC-DC converter are studied. The controller in this system combines an instantaneous current feedback loop using hysteresis with a proportional-integral algorithm to regulate the output voltage of the converter. Based on a large-signal averaged model of the converter, the stability-in-large around the operation point is presented. The complete analysis is carried out considering a buck DC-DC converter operating with a constant power load. Simulations and experimental results are provided to verify the analysis.
