PROBLEM TO BE SOLVED: To provide a battery simulator capable of excellently performing control of an upper limit and a lower limit of an output voltage.SOLUTION: A load current value of a power source part generating a DC voltage, according to a command value and supplying to a load and a power running current control value are compared; a proportionate integration calculation is carried out, according to the comparison result; and a value among the calculation results, where the load current value exceeds the power running current limit value, is selected as a correction value to the command value. Meanwhile, the load current value of the power source part and a regenerative current control value are compared; a proportionate integration calculation is performed on the value of the above comparison result; and among the calculation result, a value where the load current value does not satisfy the regenerative current limit value is selected as a correction value to the command value. Since the proportionate integration calculations are continuously carried out, a delay due to an integration time, when a first proportionate integration calculation result is not output, and the effects on the calculation result due to noise is less apt to occur. |
