| 摘 要： | 为选取合适的逆变器拓扑结构,从开关器件功率的概念出发,对3种逆变器拓扑结构在光伏发电系统中的应用进行比较.理论上计算出传统逆变器和在不同的直通状态控制下的Z源逆变器的开关器件总功率,通过Matlab软件仿真比较了3种逆变器拓扑结构中的开关器件总功率.最后给出的Simulink仿真实验证明,为在光伏发电系统设计中选择合适的拓扑结构,提供了参考与理论依据.

| Abstract: | One of critical problems that how to choose the fit topology of inverter in PV system design must be considered.Voltage-source inverter,DC-DC boosted inverter,and Z-source inverter have their own features.Based on SDP(Switching Device Power),there is a quantitative comparison that included Total Switching Device Power of three topologies at this paper.And the comparison showed that Z-source inverter is very promising in PV system application when the range of boost factor was from 1 to 2.1.Especially when p... |
