7.1 UPS in normal mode
When UPS runs normally, after high-frequency harmonic noise in utility
power is filtered by the filter, utility power charges the battery pack via the
charger and keeps battery power at full voltage level, while utility power is
converted to DC power via the rectifier and is converted into pure sine wave
power via the inverter, feeding the load via the static switch and filter.
