PROBLEM TO BE SOLVED: To secure the reliability of a gate signal while reducing the cost and cubic volume of a control device of a power converter.SOLUTION: A control device of a power converter in an embodiment comprises: a first control computation device for computing an output command value of the power converter comprising a main circuit including a semiconductor switching element; and a second control computation device for converting the output command value into a gate signal for the semiconductor switching element. The output command value is transmitted from the first control computation device to the second control computation device by radio communication. The second control computation device transmits the gate signal into which the transmitted output command value is converted to a gate substrate that drives the semiconductor switching element on the basis of the gate signal.SELECTED DRAWING: Figure 1 【課題】電力変換器の制御装置にかかるコストと体積を低減しつつ、ゲート信号の信頼性を確保する。【解決手段】実施形態における電力変換器の制御装置は、半導体スイッチング素子を含む主回路を有する電力変換器の出力指令値を演算する第１の制御演算装置と、前記出力指令値を前記半導体スイッチング素子のゲート信号に変換する第２の制御演算装置とを備え、前記出力指令値は、無線通信により前記第１の制御演算装置から前記第２の制御演算装置に伝送され、前記第２の制御演算装置は、前記伝送された前記出力指令値から変換した前記ゲート信号を、当該ゲート信号に基づいて前記半導体スイッチング素子を駆動するゲート基板に伝送する。【選択図】図１
