1. A system for operating uninterruptible power supplies (UPSs), the system comprising:
a plurality of capacitor banks;
a UPS control circuit coupled to the plurality of capacitor banks, the UPS control circuit configured to:
cause an output of a clean electrical power, wherein the clean electrical power corresponds to an electrical power having voltage fluctuations smoothed out;
sample the clean electrical power at a predetermined sample rate;
calculate control algorithm outputs based on the sampled clean electrical power; and
output control algorithm results corresponding to the calculated control algorithm outputs to a central control circuit, wherein the central control circuit is remote and distinct from the UPS control circuit; and
the central control circuit executing a trained machine learning model configured to:
detect a degradation of the plurality of capacitor banks beyond a health threshold based on the control algorithm results such that the trained machine learning model detects the degradation as a function of at least a number of events when a reverse voltage is applied on the plurality of capacitor banks and a number of events when an excessive voltage is applied on the plurality of capacitor banks; and
transmit a service alert in response to the detection of the degradation of the plurality of capacitor banks.
