Theoretical input inrush current versus time at Ui 255 Vrms
and 115 Vrms, Rext = 0.
Power Factor, Harmonics
Power factor correction is achieved by controlling the input
current waveform synchronously with the input voltage
waveform. The power factor control is active under all oper-
ating conditions.
