電装置。 A battery charging device that converts a single-phase or three-phase AC power supply forward by controlling the firing angle of a thyristor, and charges a battery with the resulting DC current. The central processing unit is backed up and controls firing of the thyristor, and the central processing unit detects the zero cross point of one phase serving as a reference among the phases of the single-phase or three-phase AC power supply, and The 0-cross point of the phase is determined by calculation, the firing angle control is performed based on the 1-phase 0-cross point or the calculated 0-cross point, and the timing operation for switching the charging voltage setting value and the above-mentioned A battery charging device characterized in that a gate pulse generation process for a thyristor is performed based on a preset program.
