一种开关电源输出电容ESR的在线无损监测技术

There are many types of switched-mode power supplies (SMPSs) with complex structures. The output filter of an SMPS often uses an electrolytic capacitor. When using these capacitors, it is very common that the capacitance decreases and the equivalent series resistance (ESR) increases. The present monitoring technique for the parameters of the output capacitor is mainly focused on a single topology ...
