PURPOSE:To provide preferable power transmission by switching the detector and setting unit gain in response to the starting state of converter group. CONSTITUTION:An electric power is controlled to constant by switching the gain of detector and setting unit in response to the operating converter group number with a gain converter 18 provided with power setting value. That is, when the converter 2 is stopped during the operation of the converters 1, 2, the electric power can be retained constant by multiplying it double at the gain converter 18. |
