Abstract
A control system comprises a DC/DC converter that includes first and second inductances, that receives a first DC voltage and that generates a second DC voltage. A control module selectively charges or discharges the first inductance while discharging or charging the second inductance during a first mode and one of charges both of the first and second inductances or discharges both of the first and second inductances during a second mode.
