1. A power conditioning system comprising:
a converter comprising a plurality of inverters disposed in the form of power electronics building blocks (PEBBs); and
a system controller that controls the plurality of inverters to operate the plurality of inverters independently of one another, receives state information from each of the plurality of PEBBs, detects a specific PEBB requiring maintenance according to the received state information, deactivates an inverter of the specific PEBB separately from remaining PEBBs of the plurality of PEBBs when the specific PEBB is detected, and controls the operation of the remaining PEBBs to continuously operate the power conditioning system while the specific PEBB is deactivated,
wherein the converter comprises:
a first bay and a second bay, each comprising a plurality of sockets, and
wherein each PEBB comprises:
a first plug unit, coupled to a first socket of the first bay;
a second plug unit, coupled to a second socket of the second bay; and
an inverter that converts a DC current input through the first plug unit coupled to the first socket into an AC current, and outputs the AC current through the second socket coupled to the second plug unit,
wherein each socket of the plurality of sockets further comprises a locking device capable of fixing a coupling state of plug units coupled thereto, and
wherein when the specific PEBB is deactivated, the system controller controls a locking device of sockets coupled to the plug units of the specific PEBB to release a locked state so as to separate the plug units of the specific PEBB from the respective sockets.
