The development of electric power propulsion systems has provided an ample scope for appearing the abilities of power batteries. The excellent characterics of power batteries and the appearance of new battery systems will promote electric power propulsion systems going to new application fields also. The application requirements and working conditions of electric propulsion systems used in submarine,torpedo and EV are different,therefore the batteris used in which will not be identical. The most impotant problems of power batteries are improving performances and decreasing cost.

电力推进系统的发展为动力电池提供了用武之地;动力电池优异本性和新电池体系的出现又促进了电力推进系统进入新的应用领域。潜艇、鱼雷和电动车中的电力推进系统的实用要求和工作条件是不同的,其选用的电池也就各异。提高性能和降低价格是动力电池发展所面临的最重要的课题。

AC power propulsion systems have the requirements of high efficiency, low harmonics and noise. This paper introduces the principles of sinusoidal pulse width modulation (SPWM) and space vector pulse width modulation (SVPWM), discusses the dead-time insert and narrow-pulse disposal in ship propulsion applications, and realizes them based on digital signal processor (DSP) TMS320LF2407A. Computation and comparison are made in terms of experiments and harmonic analysis. The result shows that compared...
