although it contains both DC and harmonics of line frequency. Therefore, the heating value
in the load (the resistive deposition source) is the same whether the current is sine wave,
rectified sine wave or a DC voltage all of equal RMS value.
The rectified line frequency was chosen as the output format because it offers an inherent
unity power factor characteristic for the power supply. This comes about because power is
being delivered to the resistive load throughout the 60-Hertz cycle of line frequency. Since
conversion from line to output is performed at 250 kHz, there is insignificant phase shift
introduced at the 60-Hertz line frequency. The net result is input line current that is, ideally,
sinusoidal and essentially in-phase with the line voltage. This is the condition for near unity
power factor.
