Abstract

A negative pulse charge emergency supply includes rectification, a battery, an IGBT switch\ circuit, a DC / DC switch supply, a transducer detection circuit, an inverse output, a negative pulse circuit, a CPU switch control signal circuit, a CPU display circuit, a CPU patrol inspection circuit, a drive circuit, a transformer, a cooling system and three relays. It has the negative pulse charging function and adds negative pulse to discharge properly based on the charging state to improve the charge receptance.

Description

1. Technical field [0001] The present invention relates to a power supply, more particularly to an emergency power supply (EPS). 2. Background technology [0002] In recent years, with the rapid development of my country's industrial and agricultural production and the improvement of people's living standards, the required power supply has also increased rapidly. Due to lack of electricity, blackouts often occur. Emergency power supply (EPS) must be used in order to ensure the power consumption of modern office buildings, large commercial places and service places, performance scenes, hospital operation lighting, etc. during power outages. At present, there are a few domestic manufacturers producing EPS. The existing EPS uses the following four charging methods: (1) Constant current charging method. like Figure 4 As shown, it is used to adjust the output voltage of the charging device or change the resistance in series with the battery to keep the ...
