[Abstract] With the rapid growth in number of small cell, new requirements are proposed, such as zero occupation of land and easy deployment. For different application scenes, different power supply solutions are proposed, including local alternating current(AC) power supply, local direct current(DC) 48 V power supply, local AC and DC 48 V mixed power supply, DC remote feeding power supply, power over ethernet(POE) power supply, and so on. Moreover, the trends of power supply solutions for small cell are pointed out, including miniaturization, modularized, high efficiency and energy conservation, green, sharing, intelligent and interconnection.
