投饵机的开关电源和主负载电动机产生大量的EMI,使投饵机工作性能下降,故障率高。本文分析投饵机开关电源的EMI,采取多种抑制干扰措施,利用PSPICE仿真软件工具,合理地调整电路元件参数,通过电磁兼容设计使投饵机开关电源能够协调、有效地工作,提高了产品稳定性和抗干扰能力。
The switching power supply of the bait machine and the main load motor generate a large amount of EMI, which reduces the working performance of the bait machine and has a high failure rate. This article analyzes the EMI of the switching power supply of the bait machine, adopts a variety of measures to suppress the interference, and uses the PSPICE simulation software tools to reasonably adjust the parameters of the circuit components. Through the electromagnetic compatibility design, the bait machine switching power supply can work in coordination and effectively and improve the product Stability and anti-interference ability.
