On the other hand, when the output voltage of the FC converter is the output voltage of the Bat converter or more, the controller controls to boost the output voltage of the Bat converter to the output voltage of the FC converter. When the output voltage difference between the FC converter and the Bat converter is a predetermined value or less capable of turning the FC relays ON without causing welding of the FC relays, the controller turns the FC relays ON. | 04-12-2012 |
