PROBLEM TO BE SOLVED: To provide a multichannel power controller which makes it possible to reduce the power capacity of power source equipment to the required minimum.SOLUTION: The power controller 3 presets the rated power value for each of a plurality of channels, and presets the total-power upper limit value of all of the channels at each unit time. Then, at each unit time, the power controller calculates the target output value of each channel and, after completion of integration processing of all of the channels, performs the following processing in sequence starting from the channel having the largest integration value. If the integration value does not exceed a threshold value, the output of the channel in question is turned OFF during the unit time. If the integration value exceeds the threshold value and if a value, which is obtained by adding the rated power aggregate value of the channels the output of which has been turned ON and the rated power value of the load of these channels, is equal to or below the total-power upper limit value, processing is performed for adding the rated power values of these channels, processing is performed for turning these channels ON for output during the unit time, and processing is performed for subtracting 1% or 100% from the target output value integrator of these channels. If the integration value exceeds the threshold value and the value obtained by adding the rated power aggregate value and the rated power values of these channels is equal to or greater than the total-power upper limit value, the output of the channels in question is turned OFF during the unit time. |
