摘要
从能量的角度,对单级boost正激组合变换器进行了稳态分析,获得了其临界条件以及输入电流等的严格解析表达式,并以指数函数近似的方法,将上述表达式化简为非常便于利用的形式。实验结果验证了理论分析的正确性。
The steady state performance of a single stage boost forward converter is analyzed from the viewpoint of energy. Equations describing the critical conditions and input current are derived, which are simplified into quite closed form expressions by exponential approximation. The analysis is justified by experimental results.
