| Abstract: | 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 µm BCDMOS process, the IR‐drop compensating switch‐mode boost DC–DC converter occupies 6.2 mm2 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 © 2014 John Wiley & Sons, Ltd. |
