Buck converters in DC microgrid are frequently used to transform the DC voltage of high-voltage bus, and the electrolytic capacitor therein is the most vulnerable component. The analysis of capacitance degradation parameters shows that the equivalent series resistance (ESR) is the best health indicator for electrolytic capacitors, and it is of significance for online monitoring the variations in ESR values in real-time. A non-intrusive online ESR monitoring method for the output capacitor of a Buck converter is proposed, which is based on the output voltage. In this method, the AC component of inductive current is fitted by the drive signal, and the real-time online calculation model of ESR is derived by combining the AC component of output voltage. Under this scheme, the additional current sensors and high-precision trigger sampling devices are not required, and the accurate calculation of the output capacitance ESR of the Buck circuit under different working conditions can be achieved only by sampling the output voltage and combining the drive signal of the switch tube. An experimental platform for the ESR monitoring system was built, and experimental verification was also carried out. Experimental results verified the effectiveness of the proposed method.

直流微电网中Buck变换器常被用于变换高压母线直流电压,其中电解电容是最易失效的元件。电容退化参数分析表明,等效串联电阻ESR(equivalent series resistance)是电解电容的最佳健康指标,因此在线实时监测ESR的变化十分关键。针对Buck变换器提出1种基于输出电压的非侵入式在线监测输出电容ESR的方法。该方法利用驱动信号拟合出电感电流交流分量,并结合输出电压交流分量建立ESR的实时在线计算模型。该方案无需额外的电流传感器和高精度的触发采样装置,只需采样输出电压,结合开关管驱动信号,就可实现不同工作状态下Buck电路输出电容ESR的精确计算。最后,搭建了1台ESR监测系统实验平台并进行了实验验证,实验结果证明了所提方法的有效性。

直流微电网中Buck变换器常被用于变换高压母线直流电压,其中电解电容是最易失效的元件。电容退化参数分析表明,等效串联电阻ESR(equivalent series resistance)是电解电容的最佳健康指标,因此在线实时监测ESR的变化十分关键。针对Buck变换器提出1种基于输出电压的非侵入式在线监测输出电容ESR的方法。该方法利用驱动信号拟合出电感电流交流分量,并结合输出电压交流分量建立ESR的实时在线计算模型。该方案无需额外的电流传感器和高精度的触发采样装置,只需采样输出电压,结合开关管驱动信号,就可实现不同工作状态下Buck电路输出电容ESR的精确计算。最后,搭建了1台ESR监测系统实验平台并进行了实验验证,实验结果证明了所提方法的有效性。

Buck converters in DC microgrid are frequently used to transform the DC voltage of high-voltage bus, and the electrolytic capacitor therein is the most vulnerable component. The analysis of capacitance degradation parameters shows that the equivalent series resistance (ESR) is the best health indicator for electrolytic capacitors, and it is of significance for online monitoring the variations in ESR values in real-time. A non-intrusive online ESR monitoring method for the output capacitor of a Buck converter is proposed, which is based on the output voltage. In this method, the AC component of inductive current is fitted by the drive signal, and the real-time online calculation model of ESR is derived by combining the AC component of output voltage. Under this scheme, the additional current sensors and high-precision trigger sampling devices are not required, and the accurate calculation of the output capacitance ESR of the Buck circuit under different working conditions can be achieved only by sampling the output voltage and combining the drive signal of the switch tube. An experimental platform for the ESR monitoring system was built, and experimental verification was also carried out. Experimental results verified the effectiveness of the proposed method.
