MGM is introduced to solve field distributions in 3-D electron optical systems. The difference equation, the discrete form of Laplace's equation, is deduced in 3-D Cartesian coordinates. In view of the smooth effect, MGM combines Gauss-Seidel iteration with a technique known as coarse grid correction. Formulae for restriction and prolongation are deduced and expressed in terms of tensors.

本文首先阐述了开关电源、功率因数校正技术和同步整流技术的发展及现状，对DC/DC变换的拓扑结构进行了选择，确定了带有隔离的准谐振(Quasi-Resonant)反激型电路，可以有效地降低损耗；接着本文对几种常见的PFC拓扑电路进行分析对比，从中选择了BOOST型电路，对工作在临界状况下的电路进行了分析，采用跟随输入电压的升压变换新技术，减小了电感体积，同时降低了开关管的电压应力，既简单又有效地实现了功率因数校正，并发现此技术值得推广；由于反激型变换器的效率一般都较低，所以本文在传统同步整流技术基础上对其加以改进，设计出一种新颖、高效的同步整流方案。
