摘　　要：蓄电池应急电源(EPS)作为一种可靠的绿色应急供电电源,在电梯、消防、应急照明等场合发挥重要作用。介绍了EPS的基本工作原理,将电压空间矢量控制算法应用于EPS的逆变输出控制,利用Matlab仿真工具箱建立其仿真模型,搭建了相应的实验平台。利用DSP2812编写了电压SVPWM算法程序,在搭建的实验平台上进行了测试。实验结果表明电压空间矢量控制不仅保证了三相电压幅值的平衡、电压频率的稳定,而且输出电压波形总畸变率小于1.5%,有效地提高了逆变输出的电压质量。EPS as a reliable power supply plays important roles on emergency in elevator, fire protection and lighting. Principle of EPS was introduced and voltage SVPWM control algorithm was used in EPS inverter output. Voltage SVPWM algorithm procedure was implemented by DSP2812 on experiment model. The experimental results reveal that voltage magnitude and frequency are stable and the THD of output voltage is less than 1.5% by using voltage SVPWM control and the voltage quality is improved.
