The invention belongs to the technical field of power supplies and relates to a power supply circuit and a mobile power supply. The circuit comprises a voltage identification module, a control module,an energy storage source and a voltage conversion module, wherein the voltage identification module detects a required voltage signal of an external load when the external load is connected, the control module determines a charging mode of the external load according to the required voltage signal and sends a corresponding starting signal to the voltage conversion module according to the chargingmode, and charging modes are in one-to-one correspondence with starting signals, the voltage conversion module receives a discharge voltage of the energy storage source, converts the discharge voltage into the voltage of the corresponding charging mode according to the starting signal, and outputs the voltage to the external load. The circuit is advantaged in that the circuit is simple in structure and low in cost, can automatically identify the load required voltage, selects the power supply mode according to the load required voltage, and improves intelligence of the power supply.
Description
technical field [0001] The invention belongs to the technical field of power supply, and more specifically relates to a power supply circuit and a mobile power supply. Background technique [0002] With the popularization of electronic devices, the charging problem of various devices has been widely concerned, which has prompted the generation of portable power sources. Portable power supplies can replace diesel generators for sudden power outages, such as providing AC / DC for various communication devices such as Ethernet passive optical networks, passive optical networks with gigabit functions, terminal optical transmission or switches, etc. Power supply and backup solutions, but the existing portable power supply has a single function, which is difficult to meet the needs of users. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a power supply circuit and a mobile power supply to solve the problem that the portable pow...
