Article Source：Qichacha | Author：Securities Star | Issuing Time：2024.05.13
Securities Star News: According to data from Qichacha, Phoenix (301191) has obtained a new invention patent authorization, titled "An Automatic Switching Circuit with Dual Power Input". The patent application number is CN201810459589. X, and the authorization date is May 10, 2024.

Patent Abstract:

The present invention relates to the field of power supply technology and discloses an automatic switching circuit with dual power inputs, including a voltage detection circuit. The voltage detection circuit comprises a first voltage detection circuit and a second voltage detection circuit. The first voltage detection circuit is set between the first input terminal and the output terminal, and the second voltage detection circuit is set between the second input terminal and the output terminal. According to the voltage value detected by the voltage detection circuit at the first input terminal and the voltage value at the second input terminal, the first input terminal and the second input terminal are switched and controlled, ensuring that the power supply of the dual power electronic product can be continuous and normal regardless of which input is inserted when the single or dual power supply is inserted in the electronic product. Work, At the same time, it can protect against various abnormal conditions such as short circuit of subsequent loads, abnormal power consumption of electronic products, and excessive output surge current, thereby better achieving the stability and reliability of the use process of dual power electronic products.
