Grid-connected inverter circulating current

In this paper, circulating current resonance of paralleled inverters with asynchronous carriers is analyzed, which is closely related to the sideband effect of sinusoidal pulse-width modulation (SPWM). . An inverter consists of a physical layer (the hardware) and a control layer (the software) that operates on the microprocessor of the inverter (see Figure 2). The control layer takes in measurements of currents and voltages, and it generates a set of reference values to fre the semiconductor. . When connecting two parallel three-phase voltage Abstract— source inverters between the same DC power supply and AC bus, a zero-sequence circulating current will occur. The presence of these undesired currents increases the power losses and decreases the efficiency of the system. As the penetration of DPGS goes high, the grid exhibits more and more like a weak grid, giving rise to potential resonance problems. [PDF Version]
