Electric power source system

Abstract

An electric power source system includes: a first DC electric power source having a positive electrode terminal connected to a first node; a second DC electric power source having a negative electrode terminal connected to a second node; a first contactor connected between the first node and a third node; a second contactor connected between the second node and a fourth node; a third contactor connected between a negative electrode terminal of the first DC electric power source and a fifth node; a fourth contactor connected between a positive electrode terminal of the second DC electric power source and a sixth node; a first switch connected between the third node and the sixth node; a second switch connected between the fifth node and the sixth node; a third switch connected between the fourth node and the fifth node; a first voltage conversion circuit connected between the first node and the fourth node; and a second voltage conversion circuit connected between the second node and the third node.
