摘要： An indirect feedback type flyback converter that compares favorably with the direct feedback type flyback converter in controllability of secondary output voltage, wherein the converter is arranged so that a switching signal, which is induced in a secondary winding when a direct current input voltage, applied to a primary winding, is turned ON and OFF by a switching element, is smoothed by rectification and fed to a load and that an output voltage is detected using a switching signal induced in an auxiliary winding to transmit a control signal to the switching element for the purpose of stabilizing the output voltage; wherein the primary, secondary and auxiliary windings are formed on respective coil formation surfaces of a coil laminate as convoluted shaped conductor patterns disposed between a core hole at the center of the pattern and the border of the coil formation surface, with the auxiliary winding being disposed to be near the border of the coil formation surface.
摘要翻译：一种间接反馈型反激转换器，其与二次输出电压的可控性的直接反馈型反激式转换器相比较，其中转换器布置成使得当直流输入电压施加到次级绕组时被感应的开关信号初级绕组由开关元件导通和截止，通过整流平滑并馈送到负载，并且使用在辅助绕组中感应的开关信号来检测输出电压，以将控制信号发送到开关元件稳定输出电压的目的; 其特征在于，所述主绕组，辅助绕组和辅助绕组形成在线圈叠层的相应线圈形成表面上，作为设置在图案中心的芯孔与线圈形成表面的边界之间的卷曲形导体图案，辅助绕组被布置靠近线圈形成面的边界。
