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.

本论文主要对燃料电池用DC/AC变换器的主电路拓扑、脉宽调制(PWM)方式、控制系统硬件电路、控制策略以及电磁兼容(EMC)问题进行了研究。考虑到燃料电池(Fuel Cell)的特性和DC/AC变换器的应用场合，本文主要对单相DC/AC变换器做了研究。 首先，针对单相DC/AC变换器，分析了它们的主电路拓扑结构、工作原理以及脉宽调制方式。 其次，完成了DSP控制系统的软硬件设计。DC/AC变换器的控制系统硬件电路，主要包括DSP最小系统、电源系统、信号检测与调理电路、CAN通信以及SCI串口通信电路等。变换器控制策略则采用电压环控制，瞬时值电压以及有效值电压控制都采用PI调节，并且阐述了如何通过DSP实现PWM脉冲。 另外本文还研究了DC/AC变换器控制电路板的电磁兼容(EMC)问题。针对一些电磁干扰(EMI)问题，提出了相应的抑制措施。主要研究了开关电源EMI滤波器的设计方法。 最后，经过相关试验，给出了结论，也提出了今后需要进一步研究的方向。
