UPS Application Guidance
Select capacitors around the real UPS duty cycle
UPS DC-link and energy-storage stages place combined electrical and thermal stress on capacitors. Selection should account for the converter topology, voltage margin, ripple-current spectrum, cooling, enclosure temperature, mounting and required endurance.
Electrical requirements
Confirm working voltage, transient margin, required capacitance, ripple current and ESR across the intended frequency range.
Thermal and mechanical fit
Evaluate ambient and hotspot temperature, airflow, case dimensions, mounting orientation and vibration constraints.
Service conditions
Define load profile, backup cycle, charging behavior, expected endurance and replacement or maintenance requirements.
