本文介绍一种改进的脉冲幅度调制（PAM）控制技术，用于一种采用碳化硅（SiC）MOSFET逆变器励磁的内置式永磁同步电动机（IPMSM）系统。更详细地说，一个自动计划的基础上的十二步开关模式的设计实时搜索的最佳励磁角的SiC逆变器下的PAM控制技术，以尽量减少波动的d轴电机电流在dq参考帧。这种自动角励磁方案可以减少电机电流和电压的谐波，从而有助于降低电机的铁损。在实验中测量的电机相电流和电压的总谐波失真（THD）值被认为是验证所提出的PAM计划在减少电机的铁芯和铜损耗的性能。在一个额外的测试案例中，还检查了在所设计的PAM控制技术与最佳激励角下降低SiC逆变器的损耗的功效。
This study introduces a modified pulse-amplitude modulation (PAM) control technique for an interior permanent magnet synchronous motor (IPMSM) system using the silicon carbide (SiC) MOSFET inverter excitation. In more details, an automatic scheme based on a twelve-step switching pattern is designed for real-time searching the optimal excitation angle of the SiC inverter under the PAM control technique to minimize fluctuations of the d-axis motor current in the dq-reference frame. This automatic angle excitation scheme can reduce harmonics of motor current and voltage, from which it helps to decrease the motor core loss. Total harmonic distortion (THD) values of measured motor phase current and voltage in experiments are considered to validate the performance of the proposed PAM scheme in reducing the motor core and copper losses. The efficacy in lowering the loss of the SiC inverter under the designed PAM control technique with the optimal excitation angle is also examined in an additional test case.
