摘要
A switch-mode boost DC-DC converter has been developed to compensate for the IR-drop because of the finite resistance of a charging cable. The boost ratio of the DC-DC converter is adaptively controlled by an IR-drop sensing circuit to provide the required voltage level to a battery charger regardless of the cable resistance. Implemented in a 0.18 mu m BCDMOS process, the IR-drop compensating switch-mode boost DC-DC converter occupies 6.2mm(2) active area and shows the 93.2% peak efficiency. The proposed IR-drop compensating boost converter can be applied to compensate for the IR-drop of any type of charging cables. Copyright (c) 2014 John Wiley & Sons, Ltd.
