PWM control of first and second inverters that control a double-winding type rotating electric machine is performed with mode switching between asynchronous PWM and synchronous PWM. A first-group triangular wave used for the PWM control of the first inverter is switched from the asynchronous PWM to the synchronous PWM in first timing at which carrier phases of an asynchronous PWM triangular wave and a synchronous triangular wave are matched with each other. A second-group of triangular wave used for the PWM control of the second inverter is switched from the asynchronous PWM to the synchronous PWM in second timing at which the carrier phases of the asynchronous PWM triangular wave and the synchronous triangular wave are matched with each other.

Control device and control method for rotating electric machine

A data transmitting device includes: a judge code generating portion for transmitting a plurality of times a predefined code pattern indicating a head portion of transmission data, as a judge code; a start code generating portion for transmitting at least once a start code having a predefined code pattern different from the judge code, following the judge code; and a valid data generating portion for transmitting valid data, following the start code. After receiving the judge code for a predetermined number of times that is less by at least one than the number of times that the judge code is transmitted, a data receiving device enters a standby state for receiving the start code, and, after receiving the start code, receives the valid data.
