摘要
基于LM5021芯片设计了一款高效反激开关电源。从电路保护出发,设计限流电路,计算开关电源的变压器各参数并设计了反馈电路,提出了基于自驱电路高效率理念的新思想、新方法。样机测试结果表明,该设计方法具有正确性与可实现性。
A type of high efficiency flyback power supply is designed based on LM5021 chip. To achieve circuit protection, this paper designs a current-limiting circuit, calculates the transformer parameters, establishes a feedback circuit, and then presents a new idea in accordance with the efficient conception of drive circuit. The prototype tests prove the accuracy and feasibility of this design.
