Abstract

The invention relates to a high-voltage alternating-current and adjustable low-voltage direct-current type dual-output online UPS comprising a main control unit, an upper computer, a display device, a control button, a load, an inverter circuit full-bridge switch, a storage battery, urban commercial power, and a voltage regulator. The upper computer, the display device, the control button, the load 5, the inverter circuit full-bridge switch, and the urban commercial power are connected with the main control unit; and the storage battery is connected with the main control unit by the voltage regulator. The urban commercial power is connected with the storage battery; and the urban commercial power and the storage battery are connected with the load by the inverter circuit full-bridge switch. According to the online UPS, the utilization rate of the UPS can be improved; the service life of the battery can be prolonged; and the safety factor can be enhanced.

Description

technical field [0001] The invention is an on-line UPS with dual outputs of high-voltage AC and adjustable low-voltage DC, belonging to the technical field of UPS energy-saving applications. Background technique [0002] UPS (Uninterruptible Power System / Uninterruptible Power Supply), that is, uninterruptible power supply, is a system device that connects batteries (mostly lead-acid maintenance-free batteries) with the host, and converts direct current into commercial power through modular circuits such as host inverters. It is mainly used to provide stable and uninterrupted power supply to a single computer, computer network system or other power electronic equipment such as solenoid valves and pressure transmitters. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the battery inside the machine; when the mains is interrupted (accident blackout) At this t...
