摘要
设计了一种工作在不连续导电模式(DCM)下的高压输出反激变换器。详细分析了工作在连续导电模式(CCM)和DCM的反激变换器稳态输出/输入传递函数,比较了这两种模式在不同负载条件下的电压输出能力。在理论分析的基础上得出:在一定的负载条件下,工作在DCM状态的反激变换器比工作在CCM状态下的反激变换器更适合高压输出电路。在试验电路上对这一结论进行了验证。
A high-voltage output flyback converter operating in DCM was designed. Steady-state input-output voltage transfer functions of the converter in the equilibrium were analyzed in detail. And output-voltage characteristics in both CCM and DCM were compared. It is concluded that, under certain load conditions, the flyback converter operating in DCM is more suitable for high-voltage output circuit than that operating in CCM. An experimental circuit was constructed to verify the conclusion.
