System for power connection and reconnection |
摘要 |
A full float system with Transient Free Multiple Load Disconnection Reconnection (TFMLDR) is disclosed. The system is based on a concept of always connecting loads and dedicated rectifiers together, and then connect such groups (1-n) via power switching devices (C1-Cn) to a pair of busbars. A backup battery is typically connected directly to the busbars via a respective fuse (F1-Fy). The disconnection/reconnection of individual groups to a busbar can then be controlled such that no transients are produced in the system voltage. Such a system is advantageous for reconnection of a load after a disconnection due to a mains power failure. The loads present a substantial input capacitance assisting in stabilizing DC power supply to the load and this load is directly connected to a rectifying unit delivering voltage controlled power during normal mains power operation. After a disconnection of a load from the busbar and the battery by the power switching member, a reconnection will be done in the following order. The rectifier will deliver current controlled power, which then charges the input capacitance of the load up to a voltage level close to the voltage of the battery. Then a reconnection to the battery with limited inrush current will be achieved thereby obtaining a practically transient free reconnection to the battery.
