Patent ID: 6903948

Claim:
A power converter comprising: triangular wave carrier signal generation device for generating a triangular wave carrier signal during a first cycle; first sampling device for sampling a first command current value for a power conversion device during a second cycle which is set so as to become shorter than one-half the first cycle and for generating a second command current value; second sampling device for sampling, during the second cycle, a first detected current value for a load to be driven by the power conversion device and producing a second detected current value; command voltage value calculation device for calculating a command voltage value on the basis of the second command current value and the second detected current value; comparison device for producing a first pulse width modulation (PWM) signal by comparing a first command voltage value with the triangular wave carrier signal; inversion detection device for detecting inversion of the first PWM signal; and inversion inhibition device for driving the power conversion device by means of one of a second PWM signal which prevents inversion of the first PWM signal during the first cycle and a third PWM signal, on the basis of a result of detection of the inversion detection device.
