The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It puts the power supply externally and connects to the host with a line, which can reduce the size and weight of the host. Only a few devices and electrical appliances have the power supply built in the host. Inside. 9V power adapter
The input voltage frequency is the frequency range within which the power adapter can automatically track the mains and maintain synchronization. Generally, the standard frequency of the power grid is 50Hz or 60Hz, and the power adapter allows a certain range of change in the mains frequency, which is the input voltage frequency range.
The application of the power adapter in the notebook computer, the semiconductor integrated circuit (IC) used in the notebook computer requires a DC voltage. The DC voltage is used because the IC cannot work under the AC voltage of 50Hz or 60Hz, and the IC will be reversed voltage (reverse bias voltage). )damage. Generally, the fault voltage of an IC is below DC20V (DC5V～10V), and the IC can only work stably within the voltage range of the high-power power adapter specified in the product specifications. Therefore, the voltage of the power adapter that supplies the IC must be within the operating range. 9V power adapter
For charger products, some people call wall plug-in Chinese-certified power adapters as power adapters, switching power supplies, and transformers. Cell phones and laptops can be charged when they are out of power. These are the simplest. The current society of plug-in wall type Chinese certification power adapter is a fast-paced society. The current mobile power supply promotes fast and high-efficiency charging, which greatly saves time for citizens, and now all chargers on the market have high-efficiency charging Effect
