基于预充电模型和低采样频率的铁路直流支撑电容电容值估计方法

A dc-link capacitor is an important device and the vulnerable electronic part of the train converter. The capacitance decline of the dc-link capacitor is accelerated because of the influence of voltage, current, charge–discharge frequency, temperature, and other factors. This will lead to circuit performance degradation and even capacitor failures. Therefore, the capacitance estimation of dc-link ...
