摘要
提出一类自磁复位正激变换器原边电路的3种基本开关单元:正激正单元、正激负单元和正激复合单元,这些基本开关单元由开关管、磁复位二极管和变压器构成;提出基于基本单元串并联的构造正激变换器的推演方法,按照该方法可以构造出双管正激变换器和交错串并联正激变换器等现有拓扑,以及一组新的正激变换器拓扑。给出推演实例和拓扑分析,验证推演方法的有效性,并以其中的一个拓扑为例,进行实验验证。
Three basic switching cells including forward positive cell,forward negative cell and forward blending cell of forward converter with inherent demagnetizing features were proposed.All cells which consist of switching device,diode and transformer,are the basic building blocks of forward converters that use auxiliary diodes to realize natural magnetizing reset.A new method to construct forward topologies,which is based on the concept of basic cells and their series and parallel connections,was proposed.The two switches forward converter and interleaved series input parallel output forward converter were constituted from the basic cells by using the proposed method and a series of new topologies of forward converter were proposed.The analysis of one of the proposed topologies was presented and verified by an experimental prototype.
