摘要：本文介绍一种高性能的独立光伏(PV)发电系统。为使PV发电系统能更具灵活性和推广性,系统后级的功率电路,由高效的升压变换器和脉宽调制(PWM)逆变器组成。在DC-DC功率变换中,为提高常规升压变换器的转换效率,引入了高效的升压变换器,以与低压的PV阵列并联运行,并对PWM逆变器进行解耦和简化。而且为对PWM逆变器进行电压控制,文中的自适应全滑模控制(ATSMC)系统,可保持总谐波失真(THD)较小的正弦波输出电压,在输出负载变化的情况下,其电压的变化也较小。此外,还介绍了不带任何光传感器的有效太阳光跟踪器,可使PV模块直接面向太阳,以捕获最大的光辐照度和提高系统的效率。文献[1]中给出的试验结果,证实了高性能独立光伏系统的高效升压变换器,PWM逆变器控制以及有效太阳跟踪器的有效性。
This paper introduces a high-performance independent photovotaic generator system.In order to make PV generator system more flexible and popularized,post-system power circuit is made up of high-performance step-up converter and PWM inverter.During DC-DC power conversion,high-performance step-up converter is applied to run parallelly with low-voltage PV arrays,and PWM Inverter is decoupled and simplified in order to raise the conversion rate of common step-up converter.What＇s more,in order to curb a power control on PWM inverter,the ATSMC system in this paper could keep sine wave output voltage with a low THD,and its voltage changes only a little when output load changes.Besides,this paper introduces efficient sunlight tracker that doesn＇t contain any opto-sensor,thus the PV module could face directly to the sun to catch highest light irradiation and improve the efficiency of the system.In Literature I,the experiment result has proven that high-performance independent PV system,high-performance step-up converter,the control of PWM inverter as well as efficient sunlight tracker are of high performance and efficiency.
