Abstract For the scalability and reliability of the whole system, it has more advantages for several small power inverters parallel than a single high power inverter. This paper proposes a simplified control method based on virtual impedance control loop for the inverters parallel operation. It can balance the current distribution of individual inverters without communication lines, and restrain the internal circulating current. In order to verify the proposed method, the parallel topology of two inverters is introduced in this paper, and the performance of this method is also verified by simulations and experiments.

Key words： Inverter virtual impedance parallel circulating current
