Method and apparatus for parallel operation of DC voltage transformer in electronic exchanger

摘要

The power supply of the electronic switchgear divides the six shelves that make up the entire rack in the exchanger into two groups, the upper three shelves and the lower three shelves, with an air baffle located in the center of the rack for redundant power supply. In his back panel, a power cable is used to connect + 5V and -5V outputs of DC / DC converters mounted on each shelf in parallel with the same polarity.
