Abstract

<div notation="docdba" type="abstract" xml:base="/api/emi/section/2d3a2057-e595-4a18-bea9-4bd93373b35c/image" xml:lang="en"><p>An Uninterruptible Power Supply (UPS) system (500) is provided which includes an input (506) configured to receive input power, an output (508) configured to provide output power to a load, power conversion circuitry (502) coupled to the input and the output, a capacitor (518, 520) coupled to the power conversion circuitry, and a controller (504) coupled to the power conversion circuitry. The controller is configured to determine a first value indicative of an equivalent series resistance of the capacitor, determine, based on the first value, if the capacitor satisfies at least one criterion, and execute, responsive to determining that the relative value satisfies the at least one criterion, one or more actions to address degradation of the capacitor.</p></div>
