电动机驱动系统、机动车辆和相电流调节方法
摘要：
本发明涉及电动机驱动系统、机动车辆和相电流调节方法，在各个实施例中，一种电动机驱动系统(400，图4)和一种机动车辆(1000，图10)包括：适于根据逆变器控制输入产生数目为N的相电流波形(118，图1)的逆变器(404，图4)；以及，具有数目同样为N的电流传感器(502、503、504，图5)的相电流采样装置(408，图4)。每个电流传感器适于接收相电流波形之一，并且电流传感器同时适于采样相电流波形并产生代表相电流波形的振幅的数字值。所述系统和机动车辆还包括控制器(410，图4)，所述控制器适于所述数字值，执行对所述数字值的评估，并根据所述评估产生逆变器控制输入(462，图4)。
摘要（英）：

The present invention relates to electric motor drive systems, motor vehicles, and methods of phase current regulation. In various embodiments, an electric motor drive system (400, Figure 4) and a motor vehicle (1000, Figure 10) include an inverter (404, Figure 4) adapted to generate (604, Figure 6), based on inverter control inputs, a number, N, of phase current waveforms (118, Figure 1), and a phase current sampling apparatus (408, Figure 4) having a same number, N, of current sensors (502, 503, 504, Figure 5). Each of the current sensors is adapted to receive one of the phase current waveforms, and the current sensors are adapted simultaneously to sample the phase current waveforms and to generate digital values representing amplitudes of the phase current waveforms. The system and motor vehicle also include a controller (410, Figure 4) adapted to receive the digital values, to perform an evaluation of the digital values, and to generate the inverter control inputs (462, Figure 4) based on the evaluation.
