Abstract
A power circuit for regulating power transfer includes: a power converter circuit having an input and an output and arranged to be connected between a power supply and a load to regulate power transfer therebetween; an input capacitor connected across the input of the power converter circuit; a series pass element arranged to be connected between the power supply and the input capacitor; and a control circuit, operably connected with the series pass element and the power converter circuit, for controlling operation of the series pass element. The power circuit further includes an input capacitor power control circuit operably connected with the input capacitor and arranged to provide power to the input capacitor to facilitate charging of the input capacitor when a voltage across the series pass element is detected to be above a voltage threshold as a result of an increase in a voltage of the power supply.
