Power adapters are power supply voltage conversion devices for small portable electronic devices and electronic appliances. We often use them on electronic devices such as mobile phones and notebook computers. When working, the power adapter is often subject to internal and external interference. Today, the power supply manufacturer will tell you how to solve the interference problem of the power adapter.
There are three main ways to solve the interference problem of the power adapter. 1. Reduce the interference signal generated by the interference source. 2. Cut off the propagation path of the interference signal. 3. Enhance the anti-interference ability of the interfered body.
External interference to the power adapter, such as power line harmonic current, power line conduction interference, electromagnetic field radiation interference, etc., can be solved by reducing the interference.
On the one hand, it can enhance the design of the input/output filter circuit, improve the performance of the active power factor compensation (APFC) circuit, reduce the voltage and current change rates of the switching tube, rectifier and freewheeling diode, and use various soft switching circuit topology. On the other hand, strengthen the shielding effect of the casing, improve the gap leakage of the casing, and carry out good grounding treatment.
To reduce the internal interference of the power adapter, you can start from the following aspects: pay attention to single-point grounding of digital circuits and analog circuits, single-point grounding of high-current circuits and small currents, especially current and voltage sampling circuits, to reduce common resistance interference , Reduce the influence of the ground loop; pay attention to the spacing and signal properties between adjacent lines when wiring to avoid crosstalk; reduce the ground wire impedance.
