LM358 内部包括有两个独立的、高增益、内部频率补偿的双运算放大器，适 合于电源电压范围很宽的单电源使用，也适用于双电源工作模式，在推荐的工 作条件下，电源电流与电源电压无关。它的使用范围包括传感放大器、直流增 益模块和其他所有可用单电源供电的使用运算放大器的场合。 LM358 的封装形式有塑封8引线双列直插式和贴片式。-LM358-house, including two independent, high gain, internal frequency compensation of the dual op amp suitable for a wide range of supply voltage single-supply use, also applies to dual power mode, the recommended working conditions, supply current and supply voltage has nothing to do. It covers the use of sensing amplifiers, DC gain blocks and all other available the use of single power supply operational amplifier occasions. LM358 package has the form of 8-lead plastic DIP and SMD-type.

3 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 -3 the use of SVPWM algorithm TMS320LF240x realize the procedure is given below the use of SVPWM algorithm TMS320LF2407 realize an application. In the process, we assume that 200 voltage vector distribution in electrical Uout average angle of 2π scope, by changing the SVPWM modulation cycle T can change the 3-phase sine wave output frequency
