Abstract

A transformerless emergency power supply is provided, and includes an energy storage battery pack, a charger, an inverter, and a control board; The input end of the charger is connected with an external mains alternating current source, the charger is connected with an energy storage battery pack line, the inverter is connected with an energy storage battery pack line, the control board is respectively connected with data of the energy storage battery pack, the charger and the inverter; and the output end of the inverter is connected with the mains alternating current source. The invention relates to a high-power EPS emergency power supply, double chargers, double batteries and no transformers, so that the size is small, the weight is light and the cost is low.

Description

technical field [0001] The invention belongs to the field of power supply technology, and in particular relates to a transformerless emergency power supply. Background technique [0002] EPS emergency power supply has been widely used in building electrical fields and special emergency power supply occasions. With the development of society, the more informatization and modernization, the more dependent on electricity. Sudden power outages will inevitably affect people's normal life order and learning, especially for production and life that are particularly important loads. Once the power supply is interrupted, it will cause major economic losses. However, power failures are sudden and do not depend on people's will. Even if the power grid facilities are advanced, unexpected power outages are inevitable. At present, the security countermeasure of urban power supply system is generally to adopt grid-connected power supply to provide reliable power supply protection for urb...
