We introduce a sub-cell WENO reconstruction method to evaluate spatial derivatives in the high-order ADER scheme. The basic idea in our reconstruction is to use only r stencils to reconstruct the point-wise values of solutions and spatial derivatives for the 2r-1 th order ADER scheme in one dimension, while in two dimensions, the dimension-by-dimension sub-cell reconstruction approach for spatial derivatives is employed. Compared with the original ADER scheme of Toro and Titarev (2002) [2] that uses the direct derivatives of reconstructed polynomials for solutions to evaluate spatial derivatives, our method not only reduces greatly the computational costs of the ADER scheme on a given mesh, but also avoids possible numerical oscillations near discontinuities, as demonstrated by a number of one- and two-dimensional numerical tests. All these tests show that the 5th-order ADER scheme based on our sub-cell reconstruction method achieves the desired accuracy, and is essentially non-oscillatory and computationally cheaper for problems with discontinuities.

The solid high-polymer-film-type fuel cell (PEM-FC) system is used as the power supply equipment for transportation and replaces an internal combustion engine. A reduction of the environmental load is expected through the cogeneration system’s (CGS) use of the PEM-FC system as a distributed power supply to individual houses, apartments, and so forth [1–3]. The growing use of distributed power systems, such as fuel cells, the reduction of power-transmission losses, and an increase of waste heat recovery are expected. Therefore, the reduction of carbon- dioxide emission is also expected as compared to conventional energy supply methods using commercial electric power.

本論文主要對燃料電池用DC/AC變換器的主電路拓撲、脈寬調制(PWM)方式、控制系統硬件電路、控制策略以及電磁兼容(EMC)問題進行了研究。考慮到燃料電池(Fuel Cell)的特性和DC/AC變換器的應用場合，本文主要對單相DC/AC變換器做了研究。 首先，針對單相DC/AC變換器，分析了它們的主電路拓撲結構、工作原理以及脈寬調制方式。 其次，完成了DSP控制系統的軟硬件設計。DC/AC變換器的控制系統硬件電路，主要包括DSP最小系統、電源系統、信號檢測與調理電路、CAN通信以及SCI串口通信電路等。變換器控制策略則采用電壓環控制，瞬時值電壓以及有效值電壓控制都采用PI調節，并且闡述了如何通過DSP實現PWM脈沖。 另外本文還研究了DC/AC變換器控制電路板的電磁兼容(EMC)問題。針對一些電磁干擾(EMI)問題，提出了相應的抑制措施。主要研究了開關電源EMI濾波器的設計方法。 最后，經過相關試驗，給出了結論，也提出了今后需要進一步研究的方向。
