Abstract: | |
Certain advancement in the automotive embedded electronics in car and applications the capacity of the current 14 volt voltage system no longer meets the demand of the on-board devices. In order to be backward compatible with the existing 14v system and to introduce extensive modifications, a dual 14v/42v is being developed as a compromising solution to the problem. Based on the new system this article is proposes a synchronous buck/boost converter an attractive topology for 42V/14V dual voltage systems since it offers the possibility of bi-directional operation without additional components. In this paper, transient currents generated during converter startup or changes in operation modes between buck and boost are analyzed and a cost effective solution to remove the transient currents is proposed. The validity of the proposed control strategy is investigated through simulation and experiment with bi-directional converters. |
