PROBLEM TO BE SOLVED: To provide a control apparatus capable of more appropriately implementing power conversion using a plurality of power conversion devices.SOLUTION: The control apparatus is applied to a power conversion system comprising a first power conversion device that is provided between a DC power source and a motor and performs power conversion by a switching operation of a first switching element, and a second power conversion device which performs power conversion by a switching operation of a second switching element. The control apparatus discriminates whether ON/OFF switching frequencies in performing power conversion by the first switching element and the second switching element are different. If it is discriminated that the ON/OFF switching frequencies of the first switching element and the second switching element are different, a switching speed of a switching element with a higher switching frequency is made higher than a reference speed in the case where it is discriminated that the switching frequencies are equal, and a switching speed of a switching element with a lower switching frequency is made lower than the reference speed.SELECTED DRAWING: Figure 6 |
