·Composition of EPS Emergency Power Supply System

EPS Emergency Power Supply mainly uses SPWM (AC pulse with modulation) technology. The system includes rectifier chargers, battery pack, inverter, mutual switching device and other devices. Among them the inverter is the core part.The role of the rectifier is to convert AC into DC, and realize the supply of electricity from the battery power to the inverter module. The role of the inverter is to convert DC malpractices into alternating current, and consistently supply electricity to the load equipment. And mutual switching device ensures the smooth switch between the city power and the inverter output of the load. The system controller keep real-time monitoring of the entire system, and may issue a warning signal, and connect the computer or Modem through the serial port to realize the computer monitoring and remote monitoring of the power supply system .
