Title:
POWER SUPPLY SYSTEM SUPPORTING REDUNDANCY BACKUP AND HOT PLUGGING
Document Type and Number:
WIPO Patent Application WO/2016/045559
Kind Code:
A1
Abstract:
A power supply system supporting redundancy backup and hot plugging comprises at least two power supply systems. Each power supply system comprises a power supply unit (1), a first control switch (2), a second control switch (3), a first controllable switch driving unit (5), a second control switch driving unit (8), a voltage comparison unit (4), a first sampling unit (6), and a second sampling unit (7). Under the condition that the power supply system is not current-shared, power supply switching can be carried out automatically, and a redundancy backup function can be achieved; and hot plugging is carried out without spark or power cut, and no other auxiliary connecting line is needed except the connection of two output voltages between the power supply systems. Power supply system switching is actively implemented by the power supply system itself, no external monitoring system is needed, and true redundancy and backup functions are achieved.
