A power supply system is provided. A power supply system includes a direct current (DC) bus, a first alternating current (AC) bus, at least one modular power conversion unit, and a battery string. The at least one modular power conversion unit includes a high-frequency direct current to alternating current (DC/AC) transformer electrically coupled between the DC bus and the first AC bus, and a direct current to direct current (DC/DC) converter electrically coupled to the high-frequency DC/AC transformer and the DC bus. The DC/DC converter is electrically coupled between the DC bus and the battery string.
