针对以删为微处理器的逆变器数字控制系统，本文在深入分析逆变电源 技术理论及实验需求的基础上，对整个硬件系统平台进行了详细的设计，研制 了一台直流输入电压24V，输出电压为AC220V、额定功率600VA的单相正弦 逆变器样机。(For to delete inverter microprocessor digital control system, in-depth analysis of this paper Inverter Theoretical and experimental basic technology needs on the entire hardware platform in detail the design, development With a DC input voltage of 24V, the output voltage is AC220V, rated single-phase sinusoidal power 600VA Inverter prototype.)

spwm逆变器的电容电流和负载电压闭环控制 花了些时间调好的 给需要的人(spwm inverter capacitor current and load voltage closed-loop control took some time to those who need a good tune)

七、 虚拟信号采集分析器 1）：利用信号发生器产生不同信号（信号的相关参数可调） 2）：在信号上叠加白噪声。 3）：对上述信号进行采样（采样频率可调） 4）：在采样的过程中利用均值滤波（每三个点取均值） 5）：显示采样后的波形，并对其进行频率分析。 6）：将采样后的波形与原波形做比较（在同一坐标系中显示） (Seven, the virtual signal acquisition Analyzer 1): different signals generated by the signal generator (signal correlation parameters adjustable) 2): white noise superimposed on the signal. 3): the said signal is sampled (sampling frequency adjustable) 4): In the process of sampling using the mean filter (averaging three points each) 5): Show the sampled waveform and its frequency analysis. 6): the sampled waveform is compared with the original waveform (shown in the same coordinate system))
