| Abstract: | LLC resonant converter was widely used in the power supply design because of its advantages of wide input voltage range, wide load variation range, and switch easily achieve ZVS, etc. In this paper, a digital power supply based on LLC resonant converter was designed. The control circuit composed of dedicated analog control chip L6599, digital potentiometer and single chip microcomputer. The design methods and processes of each component of the control circuit were described in details. And the software of control system was designed too. Various experiments verified the correctness of the designed power supply. |
