The replacement of the UPS battery pack is to use the reverse check characteristic of the diode to artificially make the voltage difference between the old and new battery packs (GB, GB'). When the new battery GB' is put in and the old battery GB is withdrawn, the diode acts as an electronic switch to supply power to the DC bus instantaneously. Thus, the circulation generated in the parallel process due to the voltage difference between the old and new batteries is avoided, and the stability of the DC power supply is ensured. It also avoids the unreliability of the DC system due to interruption of the DC bus power box during the replacement of the UPS battery pool.
