Abstract:
A device includes a transformer configured to supply a pre-charge voltage to a capacitor and a converter configured for coupling to the transformer and responsive to an increasing modulation index. The modulation index increases for a time quanta after the capacitor becomes substantially fully charged and the pre-charge voltage is substantially constant during the time quanta.
