Abstract
An alternating current (AC)-to-direct current (DC) (AC-DC) converter circuit system, and a method of designing the AC-DC converter circuit system. The AC-DC converter circuit system includes an AC-DC converter configured to receive an AC grid input from an electric power source and convert the AC grid input into DC battery power. The AC-DC converter may include a primary transformer including a plurality of field-effect transistors (FETs), and a secondary transformer configured to allow the DC battery power to be output from a grid that is allowed to have a positive value by the primary transformer.
