两路输出连续电流模式反激变压器设计

本文根据视在功率揭示变压器初级励磁电流初值、终值之比自动平衡在1/3的原理。利用初级、次级安匝平衡和次级各绕组能量占总传输能量的比,确定次级各绕组反激期间电流初值和终值。本文重点讨论CCM模式变压器的设计。

Design of Flyback Transformer with Continuing Current Model

According to the theory that the primary excitation current starting value of transformer to the final value is fixed automatically at 1/3 disclosed by apparent power, this paper takes advantage of the primary, secondary ampere-turn balance and the portion taken by each secondary winding in total transmitted energy, to determine each secondary winding＇ s starting value and final value during the flyback. And the paper focuses on the design of CCM module transformer.
