One aspect of a drive control device for controlling driving of a motor includes: a first inverter connected to one end of a winding of the motor; a second inverter connected to the other end with respect to the one end; a first control circuit for performing PWM control of the first inverter; and a second control circuit for performing PWM control of the second inverter, wherein at least one of the first control circuit and the second control circuit has a change function for changing a frequency of a carrier signal in the PWM control so as to approach a function of a carrier signal in the other PWM control with respect to the one PWM control.
驱动控制装置的一个方式是一种对马达的驱动进行控制的驱动控制装置,具备:第一逆变器,该第一逆变器与所述马达的绕组的一端连接;第二逆变器,该第二逆变器与相对于所述一端的另一端连接;第一控制电路,该第一控制电路对所述第一逆变器进行PWM控制;以及第二控制电路,该第二控制电路对所述第二逆变器进行PWM控制,所述第一控制电路和所述第二控制电路中的至少一方具有变更功能,该变更功能变更PWM控制的载波信号的频率,使其接近相当于所述一方的另一方的PWM控制的载波信号的频率。
