    摘要： This disclosure provides a contactless power reception circuit that includes a power reception part, a voltage rectifying part, a voltage transforming part and a load modulation part. The voltage transforming part includes a smoothing capacitor, a DCDC converter and a backflow prevention device. The power reception part is couplable with an electromagnetic field adjacent to the contactless power reception circuit. The rectifying part rectifies a voltage output from the power reception part, the voltage transforming part transforms rectified voltage from the rectifying part, and the load modulation circuit conducts a load modulation while signals are transmitted. The smoothing capacitor smoothes a voltage input to the voltage transforming part, the DCDC converter transforms voltage smoothed by the smoothing capacitor, and the backflow prevention device prevents backflow of charge from the smoothing capacitor while the signals are transmitted to a contactless power transmission circuit.

    摘要： A motor control unit controls a motor including a rotor and a stator facing the rotor. A current drive unit drives the motor at an axis current value of a rotating coordinate system that rotates in accordance with a control angle that is a rotational angle used in a control. An addition angle calculation unit calculates an addition angle to be added to the control angle. A control angle calculation unit obtains, at every predetermined calculation cycle, a present value of the control angle by adding the addition angle that is calculated by the addition angle calculation unit to an immediately preceding value of the control angle. A torque detection unit detects a torque that is other than a motor torque and that is applied to a drive target driven by the motor. A command torque setting unit sets a command torque to be applied to the drive target. An addition angle correction unit compares the command torque set by the command torque setting unit with the detected torque detected by the torque detection unit, and corrects the addition angle based on a comparison result.
