YG-6010 Double USB Quick Charging Car Charger

• Reduce the area surrounded by the high voltage and large current circuit, especially the primary side of the transformer, the switch tube and the power source filter capacitor circuit; Reduce the area surrounded by the output rectifier circuit and the continuous diode circuit and the dc filter circuit; Reduce the leakage inductance of the transformer and the distributed capacitance of the filter capacitor; Filter capacitor with high resonance frequency is used.
  
  
• To reduce the internal interference of the power adapter, we should start from the following aspects: pay attention to the single-point grounding of digital circuit and analog circuit, the single-point grounding of high-current circuit and low-current circuit, especially the single-point grounding of current and voltage sampling circuit, so as to reduce the common resistance interference and reduce the influence of ground ring; When wiring, pay attention to the distance between adjacent lines and signal properties to avoid crosstalk; Reduce ground resistance. For electrostatic discharge, TVS tube and corresponding grounding protection are adopted to increase the distance between the small signal circuit and the housing, or anti-static interference devices are selected to solve the problem.
  
  
• For external anti-interference capability, such as surge and lightning strike, the lightning protection capability of ac input port and dc output port should be optimized. The combination of zno varistor and gas discharge tube can be used to solve lightning strike
