Abstract

See full text

An energy storage (ES) circuit, including: a plurality of terminals configured to: connect to a pulse load having an input voltage and drawing a low current during a first interval and a high current during a second interval; and connect to a power supply having a source voltage and delivering a source current; an energy storage capacitor connected to the plurality of terminals; and a bidirectional direct current (DC) to DC converter configured to: recharge, during at least a portion of the first interval, the energy storage capacitor using a plurality of charge drawn from the source current; and reduce a drop in the input voltage during the second interval by delivering a difference between the source current and the high current to the pulse load using the plurality of charge stored in the energy storage capacitor.
