| 摘 要： | 在电动汽车等应用中，低电压和大电流的特点使得永磁同步电动机的驱动电路不同于一般通用驱动器。基于DSP TMS320F2812以及IR2110等核心芯片，在系统整体方案、功率电路、抗电磁干扰以及二次隔离电源等方面需要针对该特点进行了设计。在轴角变换的基础上采用空间矢量SFWM实现电机的控制。同时采用负偏压悬浮驱动等电路结构形式，简化了二次隔离电源的设计

| Abstract: | In some applications like electric vehicles, the features of low DC voltage supply and high-current make the drive of permanent-magnet Synchronous motors (PMSM) different from that of general-purpose inverters. This paper discussed the designs of the system structure, the power circuit topology, the EMC design and the isolated power supply circuit catering for the features, based on the DSP TMS320F2812 and some other core ICs like IR2110. The space-vector SPWM technique is used based on the digital angles from the resolver-to-digital circuit. And the floating IGBT drive circuit topology with negative bias is adopted to simplify the isolated power supply circuit. |
