Integrated power source device for inputting alternating-current power source and control method thereof

Abstract

The invention relates to an uninterruptible power source device and a control method thereof. The power source device comprises a first circuit and a second circuit. The first circuit comprises a first battery and a first bus capacitor. The second circuit comprises a second battery and a second bus capacitor, wherein the method comprises the steps as follows: both the first battery and the second battery are connected to a neutral line connected with N lines of electric supply; the second circuit works in a work mode for charging the second battery by the second bus capacitor when the first circuit works in a mode for charging the first bus capacitor, and the first circuit works in the work mode for charging the first battery by the first bus capacitor when the second circuit works in the mode for charging the second bus capacitor. The integrated power source device of the invention can save expenditure and size of the charger. Above all, the charger realized by the invention is an intelligent charger, which can correctly detect and control charging current and can supply heavy charging current.

Description

technical field [0001] The invention relates to the field of power supply technology, in particular to an AC power input integrated power supply device and a control method thereof. Background technique [0002] At present, power supply devices are usually used to ensure that various electrical equipment continue to work for a period of time after a power outage so that users can deal with them urgently, so that users will not affect their work or lose data due to power outages. In the application of computer system, network and communication, the power supply device mainly plays two roles: one is emergency use, preventing sudden power failure from affecting normal work and causing damage to the system; "Power pollution" such as low voltage, instantaneous low voltage, wire noise and frequency deviation, improve power quality, and provide high-quality power for the system. [0003] The power supply device usually has its inverter in working condition. First, it converts the ...

Problems solved by technology

[0005] However, the power supply device in the prior art mainly integrates the AC / DC converter and the DC / DC boost converter, but users have higher and higher requirements on the size of electronic equipment, and users hope that the size of the power supply device will be further reduced. Therefore, the existing integrated power supply unit has been unable to meet the user's requirements for reducing the cost and size of the power supply unit
