Abstract
In the control apparatus of an AC/DC power converter, the occurrence of a single-phase line-open in the AC power line is detected by an open-circuit detector so that a detection signal is generated. The control angle of a converter on the side of occurrence of the single-phase line-open is kept at a given value based on the detection signal. At the same time, the current set value of the automatic current regulator is also kept at a fixed value based on the detection signal.
