摘要： PROBLEM TO BE SOLVED: To solve a problem that, when a vehicle speed is high, and an electromotive force is higher than a DC-side voltage of an inverter, a copper loss and an inverter loss may be generated even at coasting, since a motor current cannot be lowered to zero even if all valve devices of the inverter are turned off at the coasting, in an electric vehicle applied with a permanent magnet synchronous motor. SOLUTION: When the electric vehicle is transited to a coasting state from a powering state or a regenerating state, a converter is controlled when the electromotive force is higher than the DC-side voltage of the inverter, and a DC voltage is raised on the basis of a DC voltage command Vdc* during the coasting. By this, since the motor current can be lowered to zero at the coating, the copper loss and the inverter loss can be suppressed. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题为了解决当车速高并且电动势高于逆变器的直流侧电压的问题时，即使在滑行时也可能产生铜损和逆变器损失即使在施加永磁同步电动机的电动车辆中，即使逆变器的所有阀装置在滑行时都被关闭，电机电流也不能降低为零。解决方案：当电动车从动力状态或再生状态转变到滑行状态时，当电动势高于逆变器的直流侧电压时，转换器被控制，直流电压升高基于滑行期间的直流电压指令Vdc *。由此，由于电镀电流可以降低为零，所以可以抑制铜损和逆变器损耗。版权所有（C）2009，JPO＆INPIT
