摘　　要：为满足实验室中光伏逆变器综合性能测试的需要,提出一种新型的大功率光伏电池阵列模拟器。分析了输出的I-V特性曲线指令信号的运算方法,利用三相电压型高频PWM整流电路实现指令信号的功率放大,介绍了光伏电池阵列模拟器的控制方案。仿真结果表明该光伏电池阵列模拟器具有很好的稳态与动态性能。In order to accurately test the comprehensive performance for PV inverters, a novel large capacity PV array simulator that can provide relatively vivid operation setting and arbitrary condition was proposed. The calculation method of referrence I-V characteristic curve was presented, the power of dictate signal was amplified utilizing high frequency PMW rectifier of three phase voltage source. The system scheme, the PV array simulator were discussed in detail. The simulated results performance of the PV array simulator. the topology, and the control strategy of indicate excellent steady and dynamic
