However, unlike ‘traditional’ grid-connected machines, such inverters inherently produce high-frequency, large-amplitude common-mode voltage waveforms, unless specific design measures are taken.
(S = 1:32 + 22) is equal to 2:4 kVA which is 77% of the apparent power during Normal operation (SN = 3:1 KV A). It can be seen that the current of the inverter remains within its nominal current. Sag II It consists of a three-phase voltage sag of 70% as shown in Fig. 10(a).
As a result, if the calculated current reference of the 3L-NPC inverter is larger than its nominal current, the controller reduces the active power to give the priority to the reactive power require-ment. The active power reference (P sagI) is then compared with extracted power from individual PV strings as depicted in Fig. 5.
