UNINTERRUPTIBLE POWER OF THE POSSIBILITY OF ENERGY RECOVERY

摘要

The uninterruptible power supply of secondary sources for testing spacecraft power relates to electrical engineering and can be used during ground tests spacecraft electrical systems. Target Utility Model - expansion capability, and improved operational characteristics of the UPS, by allowing the recovery of surplus electricity load in the AC network. The problem is solved in that the uninterruptible power supply for the test secondary sources spacecraft power running mode double conversion and containing AC converter connected to AC power, an inverter connected to the regenerative type load, a DC bus between said transducer and an inverter, which is thus connected to charge-discharge device connected to a battery, an AC converter vypo ying a bidirectional DC converter, a DC bus is further connected to a unit of ballast resistors. 1 yl.
