Photoflash capacitors need to be charged to voltages as high as 350V in low-voltage battery-powered portable devices. With the decreasing size of digital cameras, existing solutions are too large.

Specifically, the thesis will focus on minimizing the solution size, given an input current, in addition to keeping efficiency acceptable.","abstract_html":"This thesis develops an optimal strategy for charging photoflash capacitors.
