| 摘 要： | 动态无功补偿装置主要用于电焊较多的汽车、造船等行业,用于实时补偿点焊过程中引入的无功功率.该装置是以TMS320f2806为核心处理芯片,由于此芯片的A/D接口只可接收0～3V的电压信号,而无功补偿装置的输入端的电压、电流都是50 Hz的交流信号,故需采用信号调理电路将无功补偿装置输入端的交流信号调理成TMS320f2...

| Abstract: | Dynamic reactive power compensator is mainly used in automobile,shipbuilding and other industries with more welding to compensate the reactive power introduced in the spot welding process in real time.In this paper,TMS320f2806 is used as the core controller chip in the reactive power compensator.As the A/D interface of the core can only receive 0~3V voltage signal,but the input voltage and current of the reactive power compensator are 50 Hz AC signal,so it is necessary to use signal conditioning circuit to ... |
