Zusammenfassung:	A current-sharing method based on UCC29002 relates to the technical field of power electronics. By adopting the working mode of a maximum current automatic current-sharing method in the invention, users can only adjust values of a sense resistor RSHUNT, amplification factor ACSA of a current detection amplifier, an adjusting resistor RADJ and error amplifier compensators REAO and CEAO according toa specific parallel system. The invention has simple peripheral circuit, high current-sharing precision, high load adjustment rate, good dynamic response, which provides a new solution for parallel operation of a DC-DC converter with +/- Sense terminal, suitable for wide promotion and application. 一种基于UCC29002的均流方法，涉及电力电子技术领域，本发明采用最大电流自动均流法的工作方式，用户可根据具体的并联系统，只需调整检测电阻R、电流检测放大器放大倍数A、调整电阻R、误差放大器补偿R和C取值即可，本发明外围电路简单、均流精度高、负载调整率高、动态响应好，为带有+/-Sense端的DC-DC转换器并联运行提供了一种全新的解决思路，适合大范围的推广和应用。
