Abstract
A method includes connecting an output of a switched capacitor converter to a battery, the switched capacitor converter comprising a first switch, a second switch, a third switch and an upper circuit connected in series, and a flying capacitor connected between a common node of the first switch and the second switch, and a common node of the third switch and the upper circuit, in a first short circuit testing step, determining whether the third switch is shorted by comparing a voltage on the common node of the third switch and the upper circuit with a first predetermined voltage reference, and in a second short circuit testing step, determining whether the first switch and the second switch are shorted by comparing a voltage on the common node of the first switch and the second switch with a second predetermined voltage reference and a third predetermined voltage reference, respectively.
