AUTOMATIC BUCK-BOOST CONVERTER FOR AUTOMOBILE USE

Debolina Dey, Gunjan J. Tetar

As the development of the in car electronics and automatic parts the capacity of the current 14 volt voltage no longer meets the demand of the on board devices. An upgrade is imminent. In order to be backward compatible with the existing 14 volt system and to introduce extensive modifications, a dual 14v/42v system is developed as a compromising solution to the problems. Based on the new system this article proposes a bi-directional DC/DC converter. Extensive study on the stability, reliability and capability, indicates that under changing power directions. This new converter is able to do a closed loop control depending upon the current value and direction.
