一种DCM反激变换器输出电容C和ESR的无损在线监测方法

In a power electronics system, an electrolytic capacitor (E-Cap) is widely used, whose performance degradation can be reflected by the change of capacitance (C) and equivalent series resistance (ESR). This paper proposes a new online C and ESR monitoring scheme for the output electrolytic capacitor in a discontinuous conduction mode (DCM) flyback converter. The mathematical relationship between th...
