| 摘 要： | 电压空间矢量脉宽调制（SVPWM）方法具有转矩脉动小、噪声低、电压利用率高等优点，在交流调速系统得到广泛应用。针对SVPWM调制方法的实现，介绍了工作原理，设计了WINDOWS下基于运动控制卡的控制算法实现，选择Windows下对 DSP2812实时控制方法。并利用VC6.0以对话框形式编制了程序，实现了交流电机的控制。

| Abstract: | Through studying the actual circuits, we analyze the reason that the phases of FSK with carriers from the same source are not continuous. Meanwhile, we also compare and analyze the power spectrum and the bandwidth of the two kinds of FSK： the continuous phase of FSK and the discontinuous phase of FSK. |
