BOOSTING CONVERTER CONTROL DEVICE, MOTOR CONTROL DEVICE, AND ELECTRIC AUTOMOBILE

摘要

PROBLEM TO BE SOLVED: To provide a boosting converter control device which can output a stable voltage form a boosting converter even at the switching of power-running operation and regeneration operation, a motor control device, and an electric automobile.

SOLUTION: A delay time from the start of an output of a signal for switching on/off-states of two transistors 11, 12 which constitute the boosting converter 10 until an output voltage of the transistor 12 is varied by the signal is measured, and a duty of the signal for switching the on/off-states of the transistors 11, 12 is corrected on the basis of the measured delay time.
