| 发明名称 | Control apparatus in motor drive system and method of controlling motor drive system | ||
| 摘要 | A control apparatus in a motor drive system includes a magnet temperature acquiring device and a step-up ratio determining device. The magnet temperature acquiring device is configured to estimate or detect a temperature of a permanent magnet provided in a rotor or a stator of a motor of the motor drive system. The motor drive system includes a power supplying device to output direct current voltage, and a voltage step-up device to increase, at a certain step-up ratio, the direct current voltage which is output from the power supplying device. The step-up ratio determining device is configured to determine the certain step-up ratio in accordance with the temperature of the permanent magnet estimated or detected by the magnet temperature acquiring device. | ||
