The voltage to fully charge is 56 X 2.6 = 146, or 36 volts above dynamovoltage. Minimum voltage of discharge = 1.8 X 56 = 100 volts, or 10volts less than that of the line. Hence, the booster need give only36 volts maximum, and is required to add 10 volts to the battery voltagetoward the end of… … MOTOR 1,197.—Diagram of compound booster connections. The machine will be larger, however, than it would be if used onlyfor charging, because the discharge current is unusually greater than thatof charge, and the current carr>ing of the armature must be great enoughto take care of the heaviest…
