移动应急电源变流器技术及其仿真研究

Mobile Emergency Power Supply Converter Technology and Its Simulation Research

针对传统移动应急电源(EPS)大都依靠车载柴油发电机组提供电能,存在噪声大、效率低等局限性,提出了一种基于PWM变换技术的新型应急移动电源。在传统三相全控桥式变流器拓扑结构的基础上,增加电容、电感和接触器等简单器件,构成一种多功能变流器,使风能、太阳能等新能源能够应用于移动应急电源系统。Matlab仿真结果表明,系统输出电能质量较高,较传统EPS有更广泛的应用范围及更优越的性能,为新一代移动应急电源的开发提供了新的思路。

Most of the traditional mobile emergency power supplies（EPS） rely on the vehicle-loaded diesel generators to provide electricity,so the limitations of high noises and low efficiency exist.The new EPS based on PWM technology is proposed.On the basis of traditional three-phase fully controlled bridge converter topology,by adding simple components,such as capacitors,inductors and contacts,the multifunctional converter is built,this makes some of the new energy resources,e.g.,wind power and solar energy can be applied in mobile emergency power supply.The result of Matlab simulation shows that the system outputs power energy features,high quality and makes the EPS more superior and offers wider applicable scopes.This provides a new concept for developing new generation mobile emergency power supplies.
