we studied the structural weak areas of an electric car bogie frame by finite element analysis. The bogie frame under consideration is a part of the standard electric car with aluminium car body. Vertical, torsional. lateral and longitudinal loadings were applied. Numerical results were compared with the experimental results. The two results are in a good agreement.

A new half bridge converter without DC offset of magnetizing current is proposed. The proposed half bridge converter can realize no DC offset of magnetizing current as well as no circulating current, and guarantee ZVS operation. Therefore it has high efficiency and high power density, especially in wide input range. The operational principle, DC conversion ratio and ZVS analysis are presented. Experimental results demonstrate that the proposed converter can achieve a significant improvement in the efficiency.

A new scheme of dimmable ballast system for the electrodeless fluorescent lamp is proposed. The proposed scheme is composed of the conventional ballast system and the wireless communication part using an EPLD. As a result, the proposed system has a dimming control capability by wireless communication technology. In this paper, wireless dimming control system for electrodeless fluorescent lamp was introduced.
