PROBLEM TO BE SOLVED: To provide a power conversion device capable of achieving high speed control by suppressing the transmission delay of information or a control signal accompanied by insulation, and achieving highly accurate control by simplifying configurations or suppressing the occurrence place of an error.SOLUTION: A control signal generation circuit 115 for generating a control signal on the basis of information related to the operation state of a converter circuit 10 is configured to operate with a high pressure system ground G1 as a reference in the same way as the converter circuit 10. Thus, the information related to the operation state of the converter circuit 10 can be input to the control signal generation circuit 115 without being insulated. Also, the control signal generated by the control signal generation circuit 115 can be input to the converter circuit 10 without being insulated. Therefore, it is possible to achieve high speed control by suppressing transmission delay accompanied by insulation as in a conventional manner. Also, it is possible to achieve highly accurate control by simplifying configurations, and suppressing the occurrence place of an error. |
