Title:
MOTOR CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2017131094
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve energy efficiency while restricting resonance of a booster circuit in a motor control device having the booster circuit, which is disposed between a battery and an inverter.SOLUTION: A motor control device (1) comprises: a booster circuit (22) electrically connected to a battery (12); and an inverter (21) one end of which is electrically connected to the booster circuit and the other end of which is electrically connected to a motor (11). The motor control device comprises control means (100) that drives the motor by controlling the inverter so as to output a square wave voltage to the motor. On the basis of a phase difference between a voltage command relating to the motor and a current relating to the motor, the control means controls the inverter such that, on condition that an operating point of the motor lies in a resonance area that is an operating area where resonance takes place in the booster circuit, a voltage polarity relating to the square wave voltage is temporally inverted.SELECTED DRAWING: Figure 10
