A simple analytical method to calculate the rms value of the dc-link capacitor current is presented in this paper. The effect of the line current ripple on the rms value of the dc-link capacitor current is considered. This yields accurate results, especially for the applications with high ...
DC bus capacitor is one of the key components in these converters due to its energy storage and fast response capabilities. However, the ripple current through the capacitor will influence its lifetime and the overall efficiency of the converter. Previous studies showed that the capacitor current ...
此外,在电容完全放电情况下能量在两电极间形成短路放电,产生很大冲击电流通过DC-Link电容,通常电解电容很难满足要求。 In addition, when the capacitor is fully discharged, the energy forms a short-circuit discharge between the two electrodes, which generates a large impact current through the DC link capa...
