This paper describes the new design and control of integrated dc-dc converter (IDC) for electric vehicles (EVs), which integrates the dc-dc converter for on-board charger (OBC), dc-dc converter for traction converter (TC), and low-voltage dc-dc converter (LDC). The proposed IDC satisfies the requirements of conventional dc-dc converter for OBC, LDC, and TC. In other words, the proposed IDC charges the high-voltage battery (HVB), converts the voltage of the HVB to the dc-link voltage to supply power to the grid. Also, proposed IDC charges a low-voltage battery (LVB) while regulating dc-link voltage to drive EV. Furthermore, proposed IDC charges HVB and LVB simultaneously. In other words, the proposed IDC satisfies the operating requirements with minimum components while maximizing the power density. Its main operations and design considerations are firstly analyzed. Then, its performance is evaluated by simulation test.
