pulse power driver

The traditional operating method of LD power driver is that the user preset the parameters of drive current such as the rate, pulse width and amplitude. The LD cannot adjust its working parameters according to the variation of its environment with this method.

传统LD驱动电源通常采用电流参数预定输入的方式，其只能输出给定脉宽、重复频率及峰值的驱动电流，这种方式注定其不能随工作环境的变化而做相应调节。

And this paper analyze the transformation of the coordinate system in motor control, vector control, and space vector pulse width modulation theory. Secondly, this paper design the hardware part of the AC servo system, including power driver board and DSP control board.

并详细解析了电机控制中的坐标系变换、矢量控制理论及空间矢量脉宽调制理论。二、设计交流伺服系统的硬件部分，包括功率驱动板和DSP控制板。
