  How to choose the right power adapter for yourself?(图1)

  1. It must be realized that the power adapter is a high-frequency, long-term electronic product, such as a mobile phone charger, which we basically use every day.

  2. The power adapter is a product that requires safety certification, and there may be short-circuit or burning during use.

  In short, users must consider quality issues when purchasing power adapters, and the quality is reliable before they can be used safely. Power Adapter

  First, 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 rate of change of the switch tube, rectifier, and freewheeling diode, and use various soft switching circuit topologies. Structure and control methods, etc.; on the other hand, strengthen the shielding effect of the case, improve the leakage of the gap of the case, and conduct a good grounding treatment. The difference between desktop and wall-mounted power adapters? In fact, it can be simply explained. The wall-mounted power adapter is the power adapter that the main body can be directly plugged into the plug-in board. The desktop power adapter is the power adapter that the body needs to be placed on the desktop. The difference between the desktop power adapter and the wall-mounted power adapter is that the desktop power adapter requires an AC cord to be connected to the mains. Power Adapter

  The plug-in type Chinese regulatory certification power adapter switching power supply refers to a power supply that uses modern electronic technology to control the time ratio of the switch tube registration and shutdown. The plug-in type Chinese regulatory certification power adapter maintains a stable output voltage. The switching power supply of the power adapter Generally composed of pulse width modulation (PWM) control IC and MOSFET, advantages: high conversion power, small size, able to operate in a wide voltage range
