Abstract

In this paper, it develops a newly designed, patented, bidirectional dc/dc converter (BDC) that interfaces a main energy storage (ES1), an auxiliary energy storage (ES2), and dc-bus of different voltage levels, for application in hybrid electric vehicle systems. The proposed converter can operate in a step-up mode (i.e., low-voltage dual-source-powering mode) and a step-down (i.e., high-voltage dc-link energy regenerating mode), both with bidirectional power flow control. This converter operation is of two modes, namely dual source powering mode and energy re-generation mode along with power flow control in both directions. And, the independent power flow controls across two sources (i.e. the dual source buck-boost mode).
