A power converter includes a first sampling device 5 which samples a first command current value for a power conversion device 2 during a second cycle and produces a second command current value; a second sampling device 6 which samples a first detected current value pertaining to a load 3 and produces a second detected current value; a command voltage value calculator 9 for calculating a command voltage value from the second command current value and the second detected current value; a comparator 11 for comparing the second command voltage value with a triangular wave carrier signal, to thereby produce a first pulse width modulation (PWM) signal; and a multi-pulse prevention device 12. The multi-pulse prevention device 12 has inversion detection device for detecting inversion of the first PWM signal, and inversion inhibition device for driving the power conversion device 2 through use of a second PWM signal which prevents inversion of the first PWM signal, on the basis of a result of detecting operation performed by the inversion detection device.
