Abstract

See full text

When the duty command value is less than or equal to a threshold value, the motor control device performs the complementary PWM control, and when the duty command value is greater than the threshold value, it sets, for the first element, a first period in which the first element remains turned on and a second period in which control is performed with a corrected duty cycle to turn off the first element for a longer period, and performs average PWM control of which average duty cycle in a total period of the first and second periods is same as a set duty cycle. The motor control device turns on the second element while the first element is turned off in the second period.
