Abstract
Some of the problems that can be caused by high crest factor (HCF) in UPSs (uninterruptible power supply systems) are outlined. It is noted that the effect of a high crest factor load on a UPS will depend on the technique used to generate the UPS output voltage. Ways to avoid problems with HCF are discussed, including load balancing, the use of a fully rated neutral conductor, the measurement of voltages at the UPS and the load, the correct rating of the UPS, and the use of a third-harmonic filter.<>
