摘要

提出了一种支持同步和外部驱动的混合门控方案的推挽变换器，并与双晶体管正激变换器进行了比较。一般的建模方面和增强解决了一个全面的调查寄生对行为的电路使用仿真。样机仿真结果与测量结果之间的良好相关性证明了等效电路的建模扩展和参数化。为这两种电路开发了低压稳压模块，在48v输入电压下工作，在15a输出电流下提供1.6 V。用计算机代数工具计算出了反映损耗分解的图形。这为新应用程序形成了一个有效的设计基础。

Comparison of low voltage topologies for voltage regulator modules

A push-pull converter equipped with a hybrid gating scheme, which supports synchronous and external driving is proposed and compared to a two-transistor forward converter. General modeling aspects and enhancements are addressed for a thorough investigation of parasitics on the behavior of the circuits using simulation. The fine correlation between simulation and measurement results gained on prototypes proves these modeling extensions and parameterization of equivalent circuits. Low voltage regulator modules were developed for both circuits, operated at 48 V input voltage and deliver 1.6 V at 15 A output current. Graphical figures reflecting the loss breakdown are given calculated by a computer algebra tool. This forms an efficient design base for new applications.
