Summary:PROBLEM TO BE SOLVED: To provide a motor control device capable of further reducing power consumption as compared with the related art.SOLUTION: The motor control device for controlling drive of a motor comprises: an inverter bridge-connected by upper and lower switching elements; a booster circuit for boosting and outputting a power supply voltage; a boost control unit for controlling boosting of the booster circuit; and a motor control circuit for controlling the upper switching element to be in an on state or an off state based on a first drive signal generated by a boosted voltage output from the booster circuit, and controlling the lower switching element to be in an on state or an off state based on a second drive signal generated by the power supply voltage. The motor control unit sets the upper switching element to the off state and the lower stage switching element to the on state during the braking control of the motor. The boost control unit stops boosting of the booster circuit during braking control of the motor.SELECTED DRAWING: Figure 1 【課題】従来と比較して、より消費電力を低減可能なモータ制御装置を提供することができる。【解決手段】モータの駆動を制御するモータ制御装置であって、上段及び下段のスイッチング素子でブリッジ接続されたインバータと、電源電圧を昇圧して出力する昇圧回路と、前記昇圧回路の昇圧を制御する昇圧制御部と、前記昇圧回路が出力する昇圧電圧により生成される第1駆動信号に基づいて前記上段のスイッチング素子をオン状態又はオフ状態に制御し、前記電源電圧により生成される第2駆動信号に基づいて前記下段のスイッチング素子をオン状態又はオフ状態に制御するモータ制御部と、を備え、前記モータ制御部は、前記モータの制動制御時において、前記上段のスイッチング素子をオフ状態とし、前記下段のスイッチング素子をオン状態とし、前記昇圧制御部は、前記モータの制動制御時において、前記昇圧回路の昇圧を停止する。【選択図】図1
