PROBLEM TO BE SOLVED: To obtain a vehicle power converter which can remove AC ripple frequency components, superposed upon an output of a pulse generator which detects the revolution of a wheel, and can utilize only the fundamental wave component as the motor frequency. SOLUTION: The output of a pulse generator 1 which detects a revolution of a wheel is inputted to a filter 12. After the phase of the output of the filter 12 is converted into an opposite phase by a phase converter 13, the output of the filter 12 is made to pass through a motor frequency converter 5, the output of the pulse generator 1 is added to the output of the motor frequency converter 5 to remove AC ripple frequency components superposed upon the output of the pulse generator 1, and a motor frequency is obtained. The sum of the motor frequency and a slip frequency pattern is inputted to a PWM inverter controller 9, to control a voltage-type PWM inverter 10. |
