<P>PROBLEM TO BE SOLVED: To provide a motor control device, a motor control system, and a motor control module, capable of achieving, in a relatively inexpensive configuration, the reliability, low loss, and low noise of switching elements and installed components by always operating the switching element with one phase so as to suppress a peak one of a recovery current running through a diode for one phase without synchronizing turning-on operations of the switching elements with two phases or more. <P>SOLUTION: The motor control system includes a PWM control signal converter which calculates a PWM control signal for driving an inverter and a PWM control signal compensator which receives a control signal of each phase from the PWM control signal converter and compensates for at least one phase control signal so as to take a predetermined time interval when the control signal of each phase makes no predetermined time interval. <P>COPYRIGHT: (C)2012,JPO&INPIT |
