Description: 利用TMS320LF240x实现SVPWM算法的程序
下面给出了利用TMS320LF2407实现SVPWM算法的一个应用程序。在该程序中，我们假设有200个电压矢量Uout 平均分布在电角度为2π的范围内，通过改变SVPWM的调制周期T可以改变输出的3相正弦波的频率。
源程序代码-use TMS320LF240x SVPWM algorithm to achieve the following procedure is the use of TMS320LF2407 SVPWM algorithm to achieve an application. In the process, we assume that 200 voltage vector Uout average in electrical distribution point for the two within by changing the modulation cycle SVPWM T can change the output 3-phase sine wave frequencies.

Description: 采样控制理论中有一个重要结论：冲量相等而形状不同的窄脉冲加在具有惯性的环节上时，其效果基本相同。PWM控制技术就是以该结论为理论基础，对半导体开关器件的导通和关断进行控制，使输出端得到一系列幅值相等而宽度不相等的脉冲，用这些脉冲来代替正弦波或其他所需要的波形。
对不了解PWM的开发人员很有帮助。-Sampling control theory have an important conclusion: the same impulse and different shapes of the narrow pulse increases with the inertia of the link, its effect is basically the same. PWM control technique is the theoretical basis for the conclusion of the semiconductor switching device and the on-off control, so that the output has been a series of equal amplitude and pulse width are not equal, use the pulse to replace the sine wave or other by waveform needs. PWM of the developers do not understand very helpful.

Description: This application report describes how to simultaneously create a sine wave, a ramp, and a dc
level with pulse-width modulated (PWM) signals from Timer_B on the MSP430 ultralow power
family of microcontrollers. PWM signals are often used to create analog signals in embedded
applications. This report shows how to create both ac signals and dc levels with PWM outputs.
The example in this report uses Timer_B on the MSP430F149, but Timer_A could also be used
in a similar manner.

It generates three-phase waveforms overall effect as a precondition to approximate the ideal circular locus motor rotating magnetic field gap for the purpose inverter different switching modes actual flux generated by the magnetic flux to approximate reference circle, they compare the results of the decision by the inverter switching, the formation of PWM waveform. This method starting the perspective of the motor, the inverter and the motor as a whole, endo polygonal approximation control the way round the motor to get a constant circular magnetic field amplitude (sinusoidal flux).
