This paper presents a distributed current control strategy for parallel-connected inverters driving a surface-mounted permanent-magnet synchronous machine with small sharing inductors. . However, when the inverters share a common DC source and AC bus, a circulating current is generated, which causes output current distortion and system power losses. These harmonic components of circulating current influence the inverter life cycle, and it can limit the power rating of the total. . rrent suppression method for parallel operation of three-phase voltage source inverters (VSI), which may be suitable for modular parallel uninterruptible power supply systems or h brid AC/DC microgrid applications.
