Electronic switch for accumulator connection in a backup power source
Original language description
The paper describes an approach to design and construction of a switching module for accumulator connection that is to be used within backup power sources for devices that are powered by the technology called Power over Ethernet. Electromechanical relaysare replaced by MOSFET transistors, as well as power diodes, in order to minimize the power losses and to increase the reliability of the appliance. Without active cooling, the module made of SMT devices can be loaded with a current up to 6 A. The switch enables switching the power output between the AC power source and the battery. It also enables recharging of the battery, switching the power off when the battery is deeply discharged and communication with the backup source?s controller. In order totest the function of the battery, the automatic switching between the power sources can be overridden. Furthermore, monitoring of several states inside the module is supported. As the authors tried to minimize the risk of accidental malfu
