Beschreibung
Zusammenfassung:	A power system has a first converter; a second converter; a first controller for generating a first command and a second command, controlling the first converter on the basis of the first command, and transmitting the second command to a second controller; and the second controller for controlling the second converter on the basis of the second command. The first controller adjusts the first command to cancel at least one of shortage and excess of second current by first current. The second controller controls the second converter on the basis of the second command when the first command is smaller than first upper limit. The second controller controls the second converter on the basis of second upper limit when the first command reaches the first upper limit.
