Abstract: A planar spiral induction coil includes a strip-shaped coil having at least one turn. The at least one turn has a width that changes as a distance from a beginning of the strip-shaped coil increases in a length direction of the strip-shaped coil. Each turn of the at least one turn has a respective width that causes an equal current to flow through each turn of the at least one turn.

Abstract: A method of compensating for reverse current leakage in an active rectifier may include advancing an output of a comparator by a predetermined period of time by applying a predetermined offset voltage to a reference voltage input to the comparator, and activating a switch based on the output of the comparator. The method may also include deactivating the switch when a predetermined time delay elapses from a point in time at which the switch was activated.
