Abstract

This paper proposes parallel control method using droop control when each other 3-phase AC/DC converter connected. DC distribution system need parallel operation for increase the single-capacity because of the capacity restriction of power semiconductors. But, circulating current make low electric power quality when parallel operational occurrences. This system apply 50[kW] DC distribution using the proposed controller when each of the power converter connected. This system confirm through the simulation and experiment. After, compared the response characteristics when each other converter of parallel operation.
