Patent number: 9964111Abstract: A motor-driven compressor includes an electric motor driven by a motor driver, which includes a switching element that converts DC voltage from a battery to AC voltage. A control unit controls the switching operation of the switching element. A temperature detector detects the temperature of the switching element.

The temperature threshold includes a first temperature threshold, corresponding to a withstand temperature of the switching element, and a second temperature threshold, which is higher than the first temperature threshold. The control unit switches the temperature threshold from the first temperature threshold to the second temperature threshold when the control unit activates a field weakening control that reduces counter electromotive force generated by the electric motor.Type: GrantFiled: December 3, 2014Date of Patent: May 8, 2018Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Junya Yano, Tsuyoshi Yamaguchi, Tatsuya Koide, Ken Suitou, Yoshiki Nagata

Patent number: 9790944Abstract: A motor-driven compressor includes an electric motor driven by a motor driver, which includes a switching element that converts DC voltage from a battery to AC voltage. A temperature detector detects the temperature of the switching element. A voltage detector detects DC voltage applied to the switching element from the battery. A control unit suspends the switching operation of the switching element when the detected temperature rises to a temperature threshold. The control unit reduces counter electromotive force generated by the electric motor. The controller changes the temperature threshold such that the temperature threshold gradually increases from when the detected DC voltage is the highest voltage in the applicable voltage range of the battery to when the detected DC voltage is the lowest voltage in the applicable voltage range.Type: GrantFiled: December 3, 2014Date of Patent: October 17, 2017Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Junya Yano, Tsuyoshi Yamaguchi, Tatsuya Koide, Ken Suitou, Yoshiki Nagata
