POWER CONDITIONING SYSTEM SUPPORTING HOT SWAPPING AND CONTROL METHOD OF POWER CONDITIONING SYSTEM

The present disclosure relates to a power conditioning system comprising: a converter including a plurality of inverters formed in the form of power electronics building blocks (PEBBs); and a system control unit for: controlling the plurality of inverters such that the plurality of inverters are driven independently of each other; receiving status information from each of the plurality of PEBBs and detecting a specific PEBB requiring maintenance according to the received status information; when the specific PEBB is detected, deactivating an inverter of the specific PEBB separately from the remaining PEBBs; and controlling the driving of the remaining PEBBs such that the power conditioning system continuously operates while the specific PEBB is inactive.
