| 摘 要： | 将模糊控制引入并联变换器均流控制技术中,对模糊控制规则以及选择模糊控制器输入变量的量化因子和输出控制量的比例因子进行了分析。提出了一种按中间电流自主均流方法。该方法减小了各相电流调节幅度,使得各相电流很快均衡。仿真实验结果表明,均流控制策略能够使得并联变换器具有良好的动态均流与负载均分特性,能够在大负载变化内良好运行。

| Abstract: | The fuzzy logical control is introduced to parallel converter's current-sharing control technology by making an in-depth research and design on current-sharing loop's fuzzy logical controller. Fuzzy logical control rules and the reasonable choice of the quantify factor of input variable and the proportion factor of output control volume are analyzed. In order to reduce ad-justable-range of current and make each module's current balance quickly, a middle current-programming automatic current-shar-ing technique is presented. Simulation results show that the proposed current-sharing eontrol method can achieve better dynamic current-sharing and load-sharing characters, and can operate well within the large adjustable-load range. |
