Abstract

A rapid charging circuit (106) for charging a power module (104) is disclosed. The power module (104) includes one or more capacitors (218). The power module is charged using an energy source (102) connected to the power module (104). The charging circuit (106) includes a control circuit adapted to maintain a constant power level at the power module (104) during charging as the voltage level across the power module increases. The control circuit includes a pulse-width modulator (210) and an inductor (216) connected in series with the power module. The pulse-width modulator (210) can control a charge level of the inductor (216). The charge level may correspond to a current level which is in accordance with a desired power level at the power module and an instantaneous voltage level across the power module (204). The inductor (216) may be adapted to limit a current level through the power module (204) to a predetermined peak level. The control circuit may be adapted to provide a current level through the power module (204) greater than a current level from said energy source (102) during at least a portion of a charging period.
