智能除湿器可以实现在封闭空间内保持空气湿度，当湿度传感器采样的信号超过设定值，就一会显示并开启除湿器进行降低湿度，包括主程序、采样程序和显示程序(The intelligent dehumidifier can keep the air humidity in the closed space. When the signal of the humidity sensor exceeds the set value, it will display and open the dehumidifier to reduce the humidity, including the main program, the sampling program and the display program.)

本模型采用矢量控制与SVPWM相结合的方法，应用在低压微电网中。直流源电压为600V，逆变器输出电压为380V，可实现稳定功率输出。模型对网侧控制策略中每一模块尽量做出了说明，方便初学者更快理解三相逆变器控制策略的实现方法，运行效果非常好。(This model adopts the method of combining vector control with SVPWM, which is applied in low voltage microgrid. The DC source voltage is 600V, and the inverter output voltage is 380V, which can achieve stable power output. Each module is explained as far as possible in the network side control strategy. It is convenient for beginners to understand the realization method of the three-phase inverter control strategy faster, and the operation effect is very good.)
