Abstract (en)
[origin: EP2007006A2] A rectification unit and a smoothing unit rectify and smooth the AC voltage from an AC power supply and generate a smooth voltage containing the waveform of a smooth voltage period corresponding to half the AC voltage period. A DC/AC conversion unit converts the smooth voltage to a drive voltage representing a pulse-width modulated alternating voltage, and supplies the drive voltage to a motor. A current detection unit detects the motor current flowing to the motor, which is current containing the waveform of the smooth voltage period and waveform distortion, and generates a current detection signal. A target speed setting unit generates a target speed signal representing the target speed of the motor. A voltage command output unit generates and outputs a voltage command signal representing the control level of the to-be-modulated signal for pulse width modulation based on the current detection signal and target speed signal. A voltage command correction unit generates a voltage command correction signal for correcting waveform distortion based on the current detection signal and target speed signal. A to-be-modulated signal generating unit and PWM generating unit add the voltage command signal and the voltage command correction signal, and generates a pulse width modulation signal.
