摘　　要：针对传统不间断电源系统体积大、效率与可靠性低的问题,文中提出一种基于新型逆变器的UPS电源系统,该系统采用Z源网络逆变器代替传统的电压源型逆变器,基于Z源升降压机制,将直通零矢量引入零电压状态矢量中,使得电压输出波形理想,从而提高了UPS性能。最后在Matlab中对所提出的基于新型逆变器的UPS电源系统进行建模仿真,并与传统UPS电源系统进行比较,验证了其有效性与优越性。In view of the problems of big volume,low efficiency and reliability of the traditional uninterruptible power system（ UPS）,this paper presents an UPS power supply system based on novel inverter. The system uses the Z source network inverter instead of the traditional voltage source inverter. The straight zero vector is introduced into the zero voltage state vector based on Z source promotion and demotion mechanism,which make the output voltage waveform ideal,and improve the performance of UPS. Finally,modeling and simulation of the proposed UPS power supply system based on novel inverter are made in the MATLAB,and compared with the traditional UPS power system,to verify its validity and superiority.
